Sales guy was great. He took the time to talk about all details & what will Alco will do. He also took photos of everything, but did not physically inspect it as it seemed not his specialty since he's in sales. He left after 2 hours approximately and said an estimate would be emailed to me in few days. Then, he called after few days saying he needs to stop by & take more photos with another "speci...

Hello, We are sorry you were not satisfied with the services offered. In regards to the photos, we use a digital measuring tool called Hover to take measurements of the home.

We pride ourselves on offering quality home improvement projects...

They flipped the breakers so that no...

Alco was also comfortable working with Hardie siding and trim board products, whereas other companies I spoke with didn't stock it or weren't particularly experienced in...

The windows that Alco recommended (among several products we were considering) are excellent, and we are extremely pleased with the quality, functionality and the looks, which nicely complement an older brick home. In addition, Alco did a fantastic job installing them. The installers are friendly and professional and clearly know what they are doing. We have had no problems, notwithstanding severa...

We have an older home (1890), and we were anxious about finding a st...
