"Colorado siding repair was so wonderful to work with. They came quickly to give us an estimate. The workers came and were SO EFFICIENT. In addition there was no mess left. We could not be happier that they were able to repair the sections without needing to replace all our siding. Thank you Colorado Siding Repair!"

"We loved working with Ernest. He answered every question I had in a very timely manner (within minutes of my text). We have 100% exterior siding (no rock or brick. Our house was a big job and Ernestâ s crew had our James Hardy siding completely finished within 2 weeks and they were able to start immediately. The crew worked non-stop except to break for lunch. I have referred a friend to GS exteriors and I will continue to refer people. I am 100% satisfied."

"Paolo and his crew were a true treat to work with. We have been doing a full house addition and remodel, and after having several setbacks, paolo and his team came in and were able to totally redo siding, trim out a covered patio, replace gutters and paint the house. They bent over backwards to make sure 1) things were done in the right order (even coming out for 1 random day to do facia before my roofers came out and put a roof on the house) and 2) Make sure that I was happy with the end product: consistently telling me "We want you to be happy- you have to live here, so lets make sure we get this right." The two man team was here long hours over a couple of weeks, always was sure to clean up well in the evening and left the house very clean at the end of the project, and were courteous to anyone else here, collaborated well with other trades, and were kind to my kids (super important in my book!). After dealing with a lot of trades during this project that were mediocre, un-responsive, and some down right rude, it was a breath of fresh air to work with someone who did excellent work, had good follow up, and listened to my ideas and made them come to life. I would highly recommend."

Siding questions, answered by experts

Professional installers typically recommend caulking between siding boards, but it depends on the material. With Hardie board and fiber cement siding, manufacturers don't recommend adding caulk because it can trap moisture in the joints or discourage flexibility in fluctuating temperatures. Consult your local siding contractor about caulking best practices before adding any to your home’s exterior.

Hail as small as 3/4 inch (about the size of a penny) can cause damage to your siding. When hail reaches 1 inch in size, you can expect to see more cracks, chips, and holes, and hail that’s 1 and 1/4 to 1 and 1/2 inches around will cause significant damage. If you see hail that’s 1 and 1/2 inches to 2 inches or more in size, the damage is likely to be extensive and possibly even dangerous.

To calculate how much siding you need for exterior walls, first measure the height and width of the rectangular walls. For the triangular gable walls, measure the width and then the height from the ground to the tallest gable point.

  • For the rectangular walls, the calculation is: length x height

  • For the triangular gable walls, the calculation is: (length x height) / 2

Once you add these up, include an additional 10% to account for any wastage.

The cost to install or replace brick or stone siding generally ranges from $10 to $50 per square foot. The final price depends on several factors, including the specific material type, local labor rates, and any necessary preparation work, such as removing old siding. For example, different types of stone have varying costs per square foot: natural stone ($4.50–$35), stone veneer ($11–$13), faux stone ($6–$9), and cultured or manufactured stone ($5–$8).

Insulated vinyl siding costs about twice as much as the cheapest form of vinyl siding, but it’s still more affordable than other types of siding, including fiber cement, wood, stone, and brick. You get a lot of bang for your buck with vinyl siding; it’s durable, it’s available in a wide range of styles and colors, and it helps lower your energy bills.
