Mainstream replaced my gutters and it looks great! They didnt leave any mess which makes me incredibly happy. They were very nice and respectful. Outstanding experience! So happy i went with this company! Looking forward to working with them in the future!

Mainstream Home Improvement did a wonderful job. They were professional and vey knowledgeable. They got us in right away. I have called so many companies trying to get estimates and repairs with no calls back or told my job wasn't big enough. Mainstream Home Improvement took the job and did fantastic work! We will be using them in the future!

I couldn't be happier! The entire team was so professional in every way. The team double and triple checked for nails in the yard after they pulled the old roof off and we still have yet to find any nails! As a mommy who naturally worries about her kids stepping on a nail in the yard, ive been so very happy about this! Also, our roof looks even better than we could have ever imagined! All our neighbors have been saying how great it looks, too! We definitely recommend mainstream! A+++++!

I have used Mainstream several times in the past 3 years as I was replacing all of the windows in my home, so a total of 20 windows. The prices are some of the lowest I could find. They didn't try to upsell me on things I didn't need (actually did the opposite for a couple of windows and advised me not to go with a more expensive option), the windows are good quality and make my home look more modern. but the main reason I'm writing this 5-star review is the customer service.

If you have any concerns, they are quick to address them and make sure you are fully satisfied. The installation team was fast and friendly. Two of the most recently installed windows had a couple of issues and Steve came out the next day after I emailed and was able to fix the issues on the spot. I am confident that my windows will be in this home for as long as I live in it, and then will continue to serve the next homeowner long after I have left. Special thanks to Spencer, Marci, Steve, and the whole Mainstream crew!
