Installation guy who was to measure was late for first appointment, said he had been directed to incorrect address. When windows came, one was missing and one was broken. A couple weeks later, the missing windows came and were installed. Per request, installer removed and replaced exterior trim that was visibly too thick when looking out of the replacement panes. There is some glue residue on one pane which I haven't figured out how to clean up yet. Per request, they replaced a torn screen, repaired some gaps in trim. Later when I was staining the new frames, I noticed some nails were protruding and needed to be set. After staining the Milgard windows, when it was time to close them one was in the left track but had slipped from the right side of the track. When I tried to align the window in the tracks, the right spring shot up damaging the side. I didn't want to force the window back in. I called the business owner who referred me to Milgard. Milgard came, snapped the broken piece of plastic in half and instructed us to glue it back with acrylic glue. The window seems to function OK.
Description of Work: Purchased 9 replacement double pane windows and 10 Milgard essence windows also had new trim built out on 6 replacement windows.

Was referred to Keystone by friends. We had old wood windows throughout our house that definitely needed to be replaced (about 17 windows). I was impressed with Michan's knowledge and design experience right away. I hoped to have a number of dated windows reshaped, which she suggested before I even brought it up. We have one room in our house that literally has almost an entire wall of windows. Michan had several suggestions for different window options with a variety of price ranges, whereas the other companies I received estimates from said I was limited to only one or two options. She really looked at our house and family to determine what would work best for us (we have young children). She was able to provide us with an option that provided the safety I wanted (those kids are very active) along with new functionality (our old windows didn't open; Michan's design allowed us to have several windows with awnings at the top, which made cooling our house much easier in the summer). The cost was right in the middle of several estimates; she did a great job of looking at ways to save us money, but still give us the aesthetic and functions we wanted. The crew was excellent - very nice, professional and really took pride in their work. They replaced our windows during a record setting cold snap that winter and were really great about making sure we knew what they were doing each day so we could plan our schedule around the work and stay warm - our comfort and convenience was a priority with these guys. They did an excellent job making sure everything was cleaned up and secured each day (the job took about four or five days if I recall correctly). We've been so happy with our new windows and have had no problems. Many compliments from everyone that comes over. I would highly recommend Keystone Windows to anyone and would definitely use them again.

Contacted early for quotation, obtained several others and was pleasantly surprised to find that Keystone was the most aggressive and clearly did so as an ongoing way method of business as it was not just a short term sale or stunt. The service was patient and responsive despite our many revisions and questions. The salespeople got right back to us with answer to questions or updates to pricing based on our changes. Pricing was compared between dealers, Keystone provided the best value and matched competitor on shipping discount. They helped walk us through the options and provided the exact specifications that matched what we wanted. Would highly recommend and would buy from again in the future.

After seeing some very expensive estimates, Keystone gave us the best overall deal. They removed eight windows including the surrounding faded woodwork, installed new Milgard windows and added new trim. Marcelo and Nelson were exceptionally skilled at both removing the old windows and setting the new ones, as well as some very nice carpentry work on the trim. We will definitely call Keystone again when we are ready to replace the rest of the windows in the house!

Installation was very good, the crews were polite punctual and the finished product is perfect. That is the only reason I would return to Keystone Windows. The service experience with Michan was awful. She was disorganized and didn't want to provide me a written quote. She had us come to the office to provide the quote and then showed up late and kept us waiting for over half an hour while she prepared the quote. She was taking phone calls all the while and made multiple mistakes requiring revisions. We had our baby along with us, so the waiting was very unpleasant and frustrating. She also made comments about our parenting skills that offended me. The final insult from Keystone came when we received a notice of contractors lien from Milgard who manufactured the windows. This means that Keystone does not pay for their windows in a timely manor, so the manufacturer then threatens to place liens against the homes of their customers. No lien was placed, but when I called Keystone about it, they dismissed me and never followed through, implying that I was silly for being concerned about a potential lien being placed on my home. They never called me back on it. All that said, the windows are very nice, the price was very good. They have a good product, but dealing with the sales end of the company was not pleasant.

The process went very well, Mike came out to review window options and helped me select the window that best suited the architecture of the house. I was very impressed with both Mike and the installers, Mike worked with me to find the right solution at the right cost and the installers were very professional in manner and in the efficiency and quality of their workmanship. I can only say I am very happy with the result. I will have addtional window and door work as I work through my projects and look forward to working with Keystone again.

The crew arrived on Friday morning quite certain (they were extra guys put on the job) it would be wrapped up by the end of the day. Several hours later in the process of removing most of the bay window, dry rot and a carpenter ant infestation was discovered. The lead discussed my options. The first being getting an exterminator to take care of the carpenter ants. Once that had been taken care of, he could continue with the install. However, he was able to continue the removal of the bay window and sliding glass door. He wrote up a change order of the extra work to be done and the cost. As there were two crews, one went to work on the demo of the bay window , which now had to be completely rebuilt. The other went to work on the sliding glass door replacement. My house was built in 1944. The previous owners were also quite "handy" and did much renovation work themselves. And it has held up for 20 years. However, when the sliding glass doors went, it was discovered that the opening was not sqaure and had to be adjusted. By the end of Friday, I did have a working sliding glass door and a big hole where my bay window used to be, now covered in plywood. With the carpenter ants taken care of, the work continued on Monday. And by the end of the day, all was finished. I really enjoyed the crew that did work on the windows. In fact, I felt bad when they discovered so many problems and had to work that much harder to finish the job. But I guess that is where the professinalism really came thru: I was informed of the problems and was consulted in what to do next and how it would be done (obviously I had to sign off on everything). And while I know the crew had expected to pop out old windows and pop in new all on a Friday (trust me, I would have loved that too!) - all the demolition, rebuild, install and clean up was done with great attitude (and good sense of humor) and attention to detail.

Our house had the original sliding windows, most of which had lost their seal. We wanted to replace them with something more energy efficient, but also do something to add some character and style to the house, which was pretty plain.Keystone sent out two salespeople to have a look and give us a bid. They told us that the owner, Michan, had a very good eye for remodeling and decor in general and had really transformed other homes with her windows and other ideas.Michan came out and went from room to room, telling us what she thought would provide the jolt of style we were looking for. After calling some of her references we decided to trust her and just go with it.We had all the windows in our house replaced with the Milgard Essence fiberglass/wood windows. They also replaced the three exterior doors. Three of the windows went into new openings. The windows upstairs were "dropped", the openings extended further down the wall to allow the required egress, but also to give the rooms a more open, airier feel. They did exactly that.The crew was very polite and kept us informed of any problems or changes necessary along the way. They were here eight days, and cleaned up each day before they left. When they were done Mike, the site foreman, went around to make sure everything was perfect and, finding a few minor defects, contacted Milgard to come out and correct them, which they have done. Michan herself came out to make sure it had all been done as she envisioned it. . I feel the windows, doors, and the quality of the work were all first rate. We are very pleased overall.
Description of Work: Keystone replaced 7 existing windows, our front entry door, rear kitchen entry door, and sliding patio door. They also installed windows in 3 new openings. They trimmed out the windows on the exterior and well as adding fir trim around the interior wood windows.

No two windows were exactly the same and some were slightly out of square requiring careful design by Michan allowing almost no change in original appearance, measurements by Mike G. and installation by Mike and Memo. Super Job! Two months of winter wind, rain and snow with no problems, Much more quiet and less drafty.

Came in to show room to check the advertised variety of windows, only to find one brand in stock to show (MGuard), other demos are old, dusty and stacked in the back. MGuard Essence was very nice. The sale person indicated that the it would be a couple of thousand more than the Tuscany, worth the upgrade as a whole project. We gave our measurements and requested a quote. Wasted time and never received a response, neither phone, email nor website. We screen the reviews again, and pretty much happened to other consumers. Perhaps it's a front for some other activities, they' are not selling windows, definitely not to us. DON'T WASTE YOUR TIME.

Estimator came to our home and after reviewing our western exposure to rain and sun and the architectural line created around our doors, described the different options we had. We received price estimates and were able to negotiate an affordable price. Due to our need for staining the doors to match our inside wood, they worked with a local provider to arrange that for us. They installed the doors shortly after they received them. Their service and workmanship was professional and excellent.

I contacted Keystone through my local True Value. I was able to set up an estimate the same week. Gary performed the estimate. He was on time for the appointment and very thorough explaining the process of the estimate and the next steps if we accept a contract. What I liked is that he wasn't trying to over sell me. We knew what we wanted and he listened to the details we offered and answered our questions. Keystone was one of two companies we narrowed our search down to, we did not go with Keystone because of cost which was $2,000-$3,000 more than the company we chose. Also, the sales person did not seem to know the fine details of egress code. For a more simple replacement, Keystone may be a good option.

The salesman arrived on-time for the estimate (mid-May). He was excellent to work with; good personality, patient and answered our questions thoroughly. He provided us a quote that was better than the other competitor and we choose to purchase at that time. He explained the process and gave us an expectation for timeframe. He said that we would have a visit for final measurements and then they would order the door and window which should only 1-2 weeks. When the items arrived they would schedule a time for installation, which could be a 4-6 weeks out but it was possible that we might be sooner if something opened up since we were a small (<1 day) job. The next scheduled visit was for final measurements. A different gentleman showed up on time and was completed quickly. He re-iterated the timeframe provided to us from the salesman. We then did not have any communication from Keystone for over 3 weeks (late June now). When I called on the weekend I was told to leave a message with the one person who schedules installation (they worked M-F). We made contact the next week and I was told the door and window had just arrived and they set me up for the next available timeslot which was July 19th. I was contacted again a few days before the 19th as a reminder. I was told that they would be onsite between 7:30 am and 8:30 am. 2 gentlemen arrived on the 19th shortly after 8:30 am. They were professional. They prepared the work environments, they replaced the window and door and then cleaned up the areas and were done around 2 pm. I am particularly pleased by the extra effort they made when working with the lock on the door. I provided the lock (it was new) and it had poor instructions, lots of parts and had to be completely pulled apart and put back together (it was setup for a door swinging in the opposite direction). They spent 30 minutes after installing it on small adjustments to make sure that the door would shut and lock perfectly smooth and easy. Overall I have been satisfied with Keystone's effect and execution. I would use and recommend this company for any door and window replacement. The price of the door was more expensive than I would prefer, but my wife chose it based on design not price and Keystone's cost to us for the door was less than the competitor. I would have prefered more pro-active communication during the process, but they responded to me quickly when I contacted them.

I stopped by the showroom to explore the styles and brands of interior doors and windows that Keystone carries. The styles on display were limited and didn't cover the unique qualities I was looking for, however the manager mentioned that the displayed items only covered a fraction of the inventory and customizable features available. Per his recommendation, I e-mailed rough measurements of the windows and doors, as well as links to photos of the styles and specs and I had in mind. We then arranged a day/time for an in-home estimate. So far, so good. The rep showed up right on time, measured the doors/windows, and helped me pinpoint catalog items that matched my needs. At the end of the 90-minute appointment, he said to expect a written estimate within a few days. That was the last I heard from him--I never received an estimate nor a follow-up call from anyone at Keystone. I got estimates from two other companies that week. In both cases, I received written estimates on the spot, as well as follow-up calls. I am accepting one of the estimates this week. Keystone's lack of initiative cost them more than $12,000 in lost business. As a homeowner, I can choose the residential and remodeling services that I can trust to provide quality products and services. Keystone not only squandered a 90 minute appointment and nearly guaranteed $12k in business, they wasted a total of 5 hours of my time spent providing them with specs, measurements and preferences that would simply hit a dead end. I strongly encourage others not to waste their time.

We got an estimate to replace all our wood windows with new double-pane wood windows. The sales person spent some time with us explaining the process and the options and our impression was quite positive. The price was moderately high for what we were expecting but were willing to pay a little more because of all the positive reviews here. We were ready to move forward the next day but could not get a call back. So we started doing more research. That's when we discovered that there are two kinds of window replacements, full-frame and inserts. Turns out the price we got was for inserts, which are relatively simple to install (~2 hours each) but the tradeoff is you get a "frame within a frame" look, and you lose a siginificant amount of glass area. When we finally got a return call, we confirmed that the quoted price was for inserts. None of this was explained up front, we had to ask. We would have been disappointed with the results had we gone forward. The inserts themselves retail for under $800 each. The quoted price added around $900 each for installation. That is fair for a full-frame install but for a two hour 'insert' job that's $450/hour. Wow. I consider this a near-miss. I don't doubt they do quality work but I feel I was nearly fleeced. Do your homework and know what you are buying.

I was put off by the fact that they couldn't fit me in that week for an estimate. I called on a Monday morning, and they scheduled me the following Tuesday. Since Washing Energy Services had already been and gone, I wanted 2 more bids. The next company I called came out the next day, and I ended up going with them.
