We stand behind our work

See what our customers have to say.
After years of wear and tear, it was time for a siding replacement. Caldek Exteriors gave us a fair quote and delivered exceptional results. We ended up going with Hardie Board, and their team's attention to detail really stood out. Our home looks brand new, and we couldn't be happier!

We had some damage from a recent storm, and Caldek came highly recommended. They were efficient, and they kept us updated throughout the repair process. Best of all, they went above and beyond by reviewing the assesment that our adjustor gave, and were able to save us a bit of money. Great work!

Caldek Exteriors was a lifesaver after a massive hailstorm damaged the siding on our home. Their team was prompt, professional, and made the entire process seamless. They even worked directly with our insurance company to ensure everything was covered. Our house looks better than ever!

"Caldek did a spectacular job installing our decking. [They] were very professional and timely and courteous. The installers Omar and Tony were very good as well. The deck was installed when I was told and took about a day and a half. I am very pleased with the product, work and price. I would certainly recommend them."
Shane Snippa
Homeowner
“Caldek installed Duradek on our deck over our garage and we are very happy with end results. When I had a concern I spoke with [them] and they addressed the issue and it’s exactly what we wanted. Our deck, stucco and railing looks awesome. Thank you Caldek!"
Lori Sackett
Homeowner
“Caldek did an excellent job on repairing and installing Duradek on our 16 ft X 14 ft deck. They removed the aluminum cladding & railing, replaced a rotted beam & joist, installed new Duradek, reinstalled the cladding & railing in just two and a half days. Also the job came in under budget. [Caldek] was very professional and courteous. Thanks for a great job!"
