Mainstream Home Improvement replaces my roof. They explained the process well, showed up when they said they would, called with updates, completed the project timely and followed up after completion to fill warranty info out. They are professional and really care that their customers are happy with their service. We recommend Mainstream to all of our Real Estate clients because we know they are honest, do a good job, and have superior customer service!

Experience was terrific from start to finish. Staff is responsive, clear in communications, job was on time, installers were so polite and worked well after 5:00 as well as Saturday to finish up. Clean up showed little evidence they were ever there. We just couldn’t be happier and will use them for our siding job when it’s time. We highly recommend Mainstream.

They did 2 different groups of window replacements 1st was porch, bedrooms, and bath. Windows looks great and porch turned out better than expected. On both orders the time it took to get the windows seem kind of long but they were special order color match. Ordered the second group of windows and they seemed to take even longer than the first group. Second set of windows were not what I expected. The windows were much smaller than the opening and they filled them in with molding, not what I expected and not like the first set of widows. Sales person did not explain this would happen he said they would fit just like the other windows. The windows also leaked air very bad. They came right out and agreed with me and said the manufacturer would come look at the windows, this is where things went very poorly and unprofessionally. When they called to make the appointment I was out of town and they told me it was probably chimney affect and that I should expect that. Funny they did not mention that during the sale. Owner came out to the house with the person from the plant and they basically said nothing was wrong with the windows but would order and put parts in to help with the chimney affect. When person came out to install parts I showed him what was really wrong, windows not pulling together when locked and was letting the air flow through. They ordered new sashes. When they came out to install the sashes I said the other windows had drafts. They looked at them and schedule another appointment. They found that they never put insulation between window frames and window opening, they also must not have caulked between window and frame. They fixed by stuffing some insulation after pulling the molding on the inside, not a very good fix if you asked me. The sales people said they would insulated between the opening and the windows. I told him this was very important to be as the old windows had terrible drafts. He agreed and said that was very important and the windows with insulation would help me save a bunch with utilities. Still have not received the sashes for the small windows which leak, nor have I received the touch up paint to cover the marks on the window frames. Can not recommend this company

Matt S.

The service was professional, quickly done, high quality and it was affordable. Their was no pressure sales pitch as well. The sales pitch was very well done, very organized and it was very informative. After the job was done, the owner went to do the final walk through to make sure that the client is satisfied.
