Vicki and John were awesome. They were attentive professional and let us know how things were going while the roof was being installed. The crew was on time, friendly and did their work intently with smiling faces. Clean up was great and we would highly recommend this company!

We had Alcor work on replacing our roof, sidings, and gutters, and we couldn't be more pleased on choosing them to do this work for us. They finished the roof on one day along with replacing 3 skylights, as well as the sidings and gutters on a separate day, and did an amazing job on everything. The crew cleaned up very nicely around our home. I definitely will recommend them to anyone considering having work done on their home and will continue to be their customer for future projects. Thank you Val and Angela, you all are great at what you do!

I had Alcor Construction replace the roof on my house as well as the garage. They worked very hard to get the job done in one day. Workers were on time, professional and very neat. Once I saw what a great job they did on my roof, I added on gutters, fascia and soffit. I am also having them replace my bathroom window. Very pleased with all the work that has been done on my property. I highly recommend Alcor and wouldn’t hesitate to use them again.

Alcor is the best! After a storm damaged our flat roof Robert and his team at Alcor did a fantastic job quickly replacing our roof and they were on time and extremely polite. I also had Alcor add gutters to our shed and do a window wrap to keep our wooden window frames from rotting. William and his crew did an equally fantastic job and went above and beyond by helping to direct the gutters into a nearby garden bed and a new rain barrel to ensure I didn’t have flooding around the shed. I do not hesitate to recommend them for any work you may need. I am keeping them on speed dial for any issues that arise in the future!

Val, the owner was able to come out and give us an estimate and complete the job in a very short time frame. He matched the roof of the gazebo to our home. The gazebo roof is beautiful!! His crew were very professional. They were prompt, covered all my plants around the perimeter of the gazebo and clean up was great. Extremely satisfied and would definitely recommend.
