  Capitol Improvements has a great team. Everything from setting up the appointment, getting a quote, to installation were easy. Lance, Seth, and Pedro were responsive to questions and concerns and got the job done smoothly.

  The process from initial walk through to final installation was smooth and stress-free. Price was very fair. Install team led by Ryan was great and he gave us some tips for maintaining our new windows.

  I found them through here and had a great experience. For my front door install, they were very communicative and thoughtful. I knew exactly what I was getting and they made everything very clear. The price was competitive. Thanks! Highly recommended!

  I am very satisfied with the extensive work recently completed on my home which included: siding replacement, removal of deck and installing a custom designed patio and shade sail, installing an egress window, whole house window and sliding door replacement, fencing, and upgraded gutters. The workers on the project were professional, hard working, available and reliable. Ryan and his team did a great job with the siding, shutters, and gutters. Lizandro and his team were the hardest group of people I ever witnessed working. They were amazing and dedicated to completing the deck demolition, egress window install and patio construction for this project to my satisfaction. They put in long days of hard work. Seth and Austin's overall coordination and management of the project kept things moving and on track throughout, and John's design for the space was perfect. I am very appreciative of everyone's efforts!

  Absolutely Beautiful Deck and Fantastic Experience! I couldn’t be happier with the company that built my new deck — they completely exceeded my expectations from start to finish. From the very first consultation, they were professional, knowledgeable, and attentive to every detail. They took the time to listen to my ideas and offered helpful suggestions that really improved the overall design. The craftsmanship is outstanding. Every board is perfectly aligned, the railings are solid and smooth, and the overall finish is absolutely beautiful. It’s clear they take a lot of pride in their work — you can see it in the quality and precision of every part of the build. Even the small details, like how the steps meet the ground and how cleanly the edges were cut, show just how skilled their team is. The crew was punctual, respectful, and always kept the work area neat and organized. They worked efficiently but never rushed, and they communicated with me throughout the process so I always knew what stage they were on. When the project was complete, they did a full walkthrough with me to make sure everything was perfect — and it was! Now that it’s done, the deck has completely transformed my backyard. It’s not just functional; it’s beautiful. The design fits my home perfectly, and I’ve already received so many compliments from friends and neighbors. It’s become my favorite place to relax and entertain. I can honestly say this is one of the best experiences I’ve had with any contractor or home improvement company. If you’re looking for a team that delivers high-quality work, excellent communication, and a stunning finished product, look no further. I highly recommend them without hesitation!

  We had them come in to do our siding and install a screen door and were really happy with the process. I hate making decisions and just asked for their advice on everything and they were honest and quick to get things done. I'm happy to know that now there is a warranty on the siding in case anything happens they said they'd come to fix it I wish they did electrical, plumbing and handyman services, I would hire them for everything.
