WINDOW INSTALLATION SPECIALISTS OF PITTSBURGH INC

Very easy to work with from start to finish, great cost, and quality work. We had all of the windows in our home replaced with ‘new construction’ Andersen Windows including all interior trim at a cost closer to what we were being quoted for vinyl replacement windows. The measurement and ordering process was very low pressure and the windows were delivered and installed on schedule. The installation crew was professional and clean and did high quality work. I’d highly recommend Window Installation Specialists.

The guys showed up around 8:30am and they were done by noon, kept the house very clean and were extremely nice

Melissa, Bill, and their install crew were amazing. They were very responsive and helpful, patiently answering all of my questions, and even recommended a contractor who rebuilt our sills in preparation. The windows, door, and flashing all look great. I will recommend them to everyone I know!

Their service is second to none. They communicated with us from the beginning and answered any & all questions we had. The installation of our windows was done in the most professional manner. The installers are company employees and great to work with. The owners and installers are like one big family. Bill the owner is present on the job. When the job was complete, they gave instruction on the operation of our new windows. From the sales call & estimate by Melissa to the installation by Bill and the crew the experience has been a very positive one. Our new windows have changed the appearance of our home.

Scheduled appointment. Melissa called to reschedule. On the rescheduled date, she just did not show up and did not call. I took off early from work to meet her. Very unprofessional.

We love our new windows. Melissa with Window Installation Specialists is easy to work with. From measuring and instillation to the clean up everything went smoothly. Great instillation crew. We wouldn't hesitate to contact them for future windows/doors.

Everything went great Bill and his crew arrived right on time.The two workers with Bill were polite and went right to work I could not believe how fast they got the old windows out Once they got the old windows out they made sure that all the old debris was all cleaned up they put plastic everywhere to make sure no dust got on floor or furniture even when they finish up they vacumed the rug they explained how to operate the windows and screens my overall experience with Bill and Melissa was great

This is my fourth experience working with Bill and Melissa. They’ve always been professional and their work is always the best. Scope of this job included replacement of a custom bay window and an over the sink window in our kitchen. I absolutely recommend Window Installation Specialists for any window or door work and I will use them again in the future.

The team was amazing from the first sales visit through delivery and installation... and even beyond that with answering and responding to questions. Would 100% recommend this company to anyone looking for windows!!!

Could not have gone any better. Windows are beautiful and the service was excellent. Owners and staff were completely professional. Price was excellent.

We had 5 windows installed. They were the Anderson 100 series Fibrex material. Everything was well done. The workers were professional, owner was here and did the install with his workers. They kept us informed during the install answered our questions and always maintained a clean work site. We are very pleased with the product and the finished appearance both inside and out.

They did a great job. They started job in time and everyone worked fast. They were very friendly and made sure everything was done right. The price was a lot less than larger window companies.

Great work crew, not creepy like some. They were professional, quick, with a great work attitude, and they did a great job.

It went so well I couldn't believe that in about five six hours I had 11 new winners in my home! The crew who did the work really took care of the rugs the dirt hardly any, they just did a superb job. I am so happy with my new windows! I would definitely have them come in again when I get new French sliding doors.

Great experience from the first consultation to the final window installation. We were dreading having our windows replaced, but were so pleased with everything, especially the installation which went very smoothly. The installers were professional and very nice. Our new windows look wonderful!

Very professional and courteous installation specialists. The owners were honest with us that the entire window did not need replaced, just the sash. They could have recommended the entire window which would have costed us thousands more. I was very impressed and will definitely use them when we have to replace the other windows.

The team was professional and courteous and the after-install clean-up was spotless. Even though our installation was done in the middle of winter, the work was done so quickly and efficiently that we didn't even really notice the cold! It was a tough decision to remove our home's original wood windows but they were in very poor shape ... I am so glad I went through with the project because the rest of the winter was draft-free and the windows are beautiful (we went with Pella Architect Series).

Bill and Melissa Kish and their installers were terrific to work with. Our job was done on-time and as-promised. The installers really went beyond my expectations as far as protecting our home and furniture from construction debris and cleaned up very well when they finished each day. We compared and got quotes from several window companies and W.I.S.P gave us by far the best value, best professionalism and best product for our job. They are clearly highly experienced and addressed a few potential issues during our initial walk-through that the other companies didn't even notice. I enthusiastically recommend them.

They were fabulous! Put drop clothes down, booties on their shoes, swept up any mess they made. The work is beautiful; it's like a new room. The woodwork they replaced around the window is just perfect. They even arranged for someone to stain the new woodwork. They had great respect for our home. They were pleasant people, too! I would highly recommend them and definitely, will use them again. They make it easy.

The window consultation and installation went very well. The sales representatives were knowledgeable and helpful during the process. Installation was fast and the workers were very nice. I would recommend this company to anyone in need of windows.

We had two windows replaced. Owners Bill and Melissa came to our home to measure and record our preferences. We were told because of high demand for windows we might not get them installed until October. To our surprise the windows came in early from Andersen and were installed the following week. Three workers arrived at 8:00 am and the windows were installed by noon. Tarps were put down and the crew did a very good job installing the windows including the trim. They cleaned up after completion and took away all of the old windows. Melissa followed up via email to confirm that we were satisfied with the installation. We can recommend WINDOW INSTALLATION SPECIALISTS OF PITTSBURGH INC 1968 MARS HILL RD, IRWIN, PA 15642!

From beginning to end it was a wonderful experience. Very knowledgeable about all window and the installation process. There is no way to beat the price for the quality of window that we received. On install day there where very professional, and in just 2 days had all 15 windows done. The installers that came really knew what they where doing and used the highest quality of installation tools like high quality caulking and composite shims. There is no way that anyone could have done a better job. We talked to 6 other window installers and as I said before they where the best on price for the quality of windows.

From beginning to end the process was amazing. Melissa was very knowledgeable and explained everything to a “T.” Things my husband and I did not get from other companies, such as not covering the lintels and how bad our old windows actually were (no screws holding them in place). The workers are very professional. Easy to talk to and all around amazing workers. I highly recommend them.

The entire process, from start to finish was flawless. We obtained bids from 3 comparable companies. Not only did window installation specialists pull off a perfect installation, they did it for thousands less than the closest competitor. I certainly would recommend them to anyone in the market for upper end windows.

Beautifully! Quality of work was impeccable, attention to detail was perfect, customer service for concerns was outstanding. I can't recommend them highly enough!
