Tower Energy International LLC

Sigma Exteriors was eventually purchased by Tower Energy International, which is a great service provider of energy efficient facilities, but no residential roofing experience.

They were the most expensive but we wanted the best - we shopped many window companies - the salesman was great - however, we are unhappy with the costliest part of the project. PS We still have windows that have not been caulked.

There was a communication and installation problem due to internal scheduling and the weather. The price was good. The quality of products were outstanding. The installation was outstanding. I am very happy and will most definitely use their service again if they will allow me.

Vince (my go to guy there) has been great and very patient with all the many questions I have on how things are done and why things look the way they do. He also walked me through everything that needed to be fixed and how they were going about doing it. Overall, I think paying the extra money to get professionals that know what they're doing than hiring a guy that just thinks of you as a job is well worth it. I would recommend working with these people if you can! I should have my roof replaced in the next month or two.

How did it go overall? As I indicated in my rating above it went bad..The "Details of my Experience" add up to an F..Now Angies List has been after this report for some time yet i waited and waited to file it in hopes that Sigma Exteriors would wrap this up.Now I began this remodeling of my home project with Sigma Exteriors in spring of 2009 with estimate and design phase begiinning actually in august 2009..which was later than i was told it would begin..This was the first delay of many over the course of the project which is not completely finished.The reason i am now filing is after talking with the owner about fact a gutter is not fastened and a window trim still remains unpainted for last several months.I get call from his people that they will "do it all at once" when paint comes in or whatever..It was just the last time i could hear the do it all at once line.Now after over a year with these people on an extensive remodel job I am uniquely qualified to file this..I am hesitant to go into the nightmare in too much detail because I want to get it finished and i want my warranties to actually be covered.Needless to say the littanny of problems,delays,excuses,and what not are a long list that i would get into should angies list require it...Suffice it to say that i am not happy had a long year and they are now making it even longer...its (March 1st, 2011) today and my $20,000 plus Weather Shield windows all across the front of my home look absolutely terrible with a weird oily pattern developing on all the glass anytime its around 40 or lower and no other windows in my neighborhood get it at anytime! The 2 pella windows i had put in during the job by another company (Verhalen) are beautiful in any temperature.

I solicited multiple contractor bids to replace 7 windows and 2 sliding patio doors. For an equitable evaluation, I made sure that each contractor bid on the exact same Marvin windows and doors, which I had already speced-out at the local Marvin distributor. I know Marvin is expensive but Sigma's bid was so over the top and no where near their competion. For example, Sigma quoted me $9,600.00 for the 2 Marvin patio doors, the company I hired was $5300.00 for the exact same doors. Sigma's total job bid was $25,400.00, the competion's bid was $11,089.00 for the exact time and materials - more than double. It left me wondering if they just didn't know how to bid a job or truly up-charged that much as their standard operating business model. Either way, it left a really bad impression. For obvious reasons, I did not select Sigma.

Halfway around my house Vince asked "what'll it take to get you to sign today?" I hadn't even explained every thing I wanted. From the ground he said my chimney looked good. And of course the ever popular-"what do you want to spend?" When I questioned something he said about the gutter/downspout he asked what I did for a living (how dare I question!). After taking measurements and pictures he wanted to set up a date for an estimate. I said I thought that was what today was for. Since I also wanted an estimate for possibly removing a partial overhang he had to confer with someone else. I found that answer acceptable as for the overhang, however he still could not give an estimate for the roof, gutters, downspouts, facia and vents. In response to company response: I never said I didn't have a lot of time. What I wanted done and what I was thinking of doing were both clearly stated (as listed previously in this report) . I don't understand what information he feels he wasn't given, other than his question of "what do you want to spend". The objective of an estimate is that I tell you what I want done and you tell me your price. He never asked to go on the roof ( which I found very odd) and never asked to see the attic. I never told him he was "wrong" about the downspout (located next to the electrical conduit), but I did ask him what the difference was since water can flow over the top of the gutter no matter where the downspout was located. That is when HE became indignant and wanted to know what I did for a living.At that point no amount of small talk was going to matter.

It took almost 3 months for this project to be done. In the middle of it, the workers drove a nail through an electrical wire shorting out half of the house, ruining several light fixtures as well as the garage door opener, but they insisted they did nothing wrong. We had to hire an electrical contractor to come out to find and prove that the nail caused the short. The work crew changed every day and some days they would arrive at 9, some days at noon, and some days not at all. They would work about 3-5 hours a day. My husband would point out things that didn't look right, but this was ignored. When the job was finally finished, the boss came around to inspect and said the job had been done wrong. Another crew was brought in who completely ripped off everything that had been done and within 2 weeks, had new all put on. Sigma did pay for replacing the fixtures and garage door opener that was burned out, gave us a deduction on the final cost, and gave us two 2 shirts for the inconvenience. It was a nightmare experience we don't EVER want to repeat.

They were very professional. They represented a variety of windows. We liked them a lot, but we didn?t use them. They were great, though.

Sigma was the last of 4 contractors I contacted to respond. The salesman who came spent a lot of time cautioning me that anyone else would not honor the offered warranty because there was no guarantee that the windows would be installed according to manufacturer specs. He was almost threatening about it. The estimate he gave me was the highest of the 4, about 50% higher than the next highest. Sigma did not do the work.

It was an excellent experience. We went with them because the guarantee and because of the service they provided. They sent someone out and sat with us just ahead if their crew and discussed everything that was going to happen over the weeks that they were going to be here. They talked with us at the end of everyday and let us know what they had done and did excellent clean up. They also replaced a small attic window and one built an aluminum window and installed it. They also had to replace the gutter. They did a great job and I was surprised with how much interaction they had with us before they started the job and the care they took. They had to come into the house to install the attic fan and the dog was here and it did not have any problem with him and he did not have a problem with it, which was unusual.

They replaced a small attic window that we had difficulty getting someone to come out and take a look at it. They built an aluminum window and installed it for us. They had to come into the house to install the attic fan and the dog was here and it did not have any problem with him and he did not have a problem with it, which was unusual.

They representative came and spent two hours with me and he ordered the wrong ventilation equipment. I got charged with that. They are probably good for big companies but I don't reccomend them for smaller home owners. I had to ask them to seal off side vents. You have to watch their work step by step.

1st took 4 months from order to install; didn't come with the ordered hardware and had to call someone. Installers uneducated on storm door install and didn't bother to read instructions on closer and did it incorrectly. Left huge gaps and several drafts in the install along with much damage to wood frame and wall. Sigma had to come and do a temporary install on hardware as this was on a Sat and no one available. Also came out 2-3 more times fixing all the problems with the install. Damage to the door frame, which includes exposed nail heads, splintered wood chunk missing, horrible caulk job, sections of dry wall ripped down 2 layers (brown paper is exposed) flaps were they tried to match up the chunks of drywall that were ripped off due to their failure to cut all the way through around the frame for removal. Disclosure statements indicate there may be damage for a door install, just didn't expect the wall to be 'ripped off'. While I may use/recommend them for windows as have had no issues with that, will not use or recommend for door install. Have another door to be replaced and will definitely use someone else.

There were a couple issues, but they were handled quickly, professionally and to our satisfaction.

The price was good compared to others. They gave us an estimate. They did a follow up on the work they did. They cleaned any mess they made. They were friendly.

We had seen their TV ads and Valpak coupons, so we thought we would get a quote. Their sales representative was very nice and professional. He came on a Saturday afternoon to show us samples, tell us about the company, take measurements, and take pictures of our house. He returned the following Saturday to give us the quote. We thought they might be the highest of the three quotes we were receiving, but we were willing to pay a bit more if we felt they had the best product and skills. "A bit more" meaning $2,000-3,000 more. Well, our jaws dropped when he gave us the quote of approximately $34,500. A few days earlier we received a quote of $16,500 from another contractor. Even more hilarious was that a few days after the Sigma quote we got a price of just over $14,000 from a third contractor, and he even used the exact same Dow insulation panels with the same "R" rating that Sigma uses! The only difference was that Sigma uses Revere brand siding, which apparently has "seamless integration" with Dow insulation panels since they have a partnership. The other contractor uses Alcoa brand siding. Anyway, we thought there was no way Sigma was providing $20,000 more in product and services. When the sales representative called a week later to see how our decision process was going, I told him about the other quote and how they use virtually the same product as Sigma. He didn't go on the offensive and was professional about it for the most part. He said he "understood our frustration", but felt that they are providing a far more superior product and superior services than any other contractor. He also said he thought it was impossible for another contractor do to our job for just over $14,000. Well, he can come over to our house anytime and see the excellent job our contractor did, for just over $14,000! He also said we should check the other contractors' references and make sure we weren't being taken for a ride. When I told him he had received the Super Service Award from Angie's List multiple times, he clamed up. I told the representative that he was very professional during the quote process, and that he was just doing his job, but that the owners of the company really need to rethink their pricing. We still can't believe they were trying to charge that much. Obviously, you are paying for their TV and Valpak advertising costs, and their "partnership" with WTMJ radio & tv. Anyway, for just under $25,000, we did the whole siding & trim job, had a new concrete patio and front walkway poured, had new glass block windows installed, and had some electrical work done. Just having the siding & trim job done by Sigma would have been $10,000 more. It just goes to show you that you need to get multiple quotes, and utilize Angie's List! Well, if you want to overpay by $20,000 or more, go with Sigma. If not, go with somebody else!!!

Had 3 windows and an exterior storm door installed in fall 2007. A few finishing issues which I put in writing to them. They were responsive to that and inspected and agreed with my assessment stating not up to their standards. Ordered 11 more windows for install (in the process). Took care of two of the fall issues and will return to finish up outside trim and complete final fall install issues. Clean up was excellent and took care not to damage new plantings in front of house. Have six windows to go and will use Sigma. Explained anything that needed to be done, such as blinds removed and how long to wait before rehang to allow caulk to set.

After paying the bill for $400 and still having a leaky roof my husband went up there which we probably should have done in the first place and saved ourselves $400, found a space near the dommer, caulked it and so far no more leaking. Now there is inside water damage which must be fixed, tearing down ceiling to replace insulation. I contacted several other roofing contractors and they said that they guarantee their repair work for 90 days and they weren't on Angie's List. Am disappointed as we thought that joining Angie's List would avoid problems like this.

My handyman was going to replace rotted exterior wood by a window, but discovered rot in the sill. I called several service providers for a bid/estimate. Each provider specified the need to replace the entire window, which would cost around $15,000. Sigma, however, suggested as an alternative replacing the wood, filling the gaps with wood hardener, and wrapping the new wood and existing wood with aluminum wrap to prevent future water damage by the windows. It even suggested going with the handyman for the repair and just letting them do the aluminum wrap, which is what I will do.

I contacted the company and they had a representative out to the house the next day. After he went up on the roof and did an inspection, located the problem, and fixed it all within 30 minutes. Very pleased with their response time and work done.

The estimate process went well. I felt that he was very thorough.

Great job and great warranty.

Their representative was very thorough and very professional. The price was way out of our range, but it seems like they install a top of the line roof!
