"We initially hired Ideal Siding to replace the vinyl siding on the rear of our home. They came for a site visit quickly, and they provided excellent advice. After speaking with Rick, he pointed out several areas where water was coming into our house, so we decided to do a complete tune-up on the siding, flashing eavestroughs and caulking around the windows. I am so pleased with the work that they did. Our house looks much better. I can’t say enough good things about their professionalism, experience, and quality of work. I will recommend Ideal Siding in the future and will continue to hire them for my future properties."

"They got done quickly and cleaned up after the work was completed. When the old siding was removed from the house, we found that there was very little insulation. The crew stopped the installation and helped install some additional insulation before installing the new siding. The crew was friendly and professional. The siding is beautiful and durable."

"Our original siding was 34 years old. They stripped it off in a few hours and replaced it with perfectly installed James Hardie fiber cement siding and trim. We now have a brand new house! Ernest and everyone we had contact with from GS were very patient, service oriented, and concerned for our satisfaction. We would recommend them unconditionally."

"All the work went well. Paulo was very professional and responsive. We had a few delays that were out of his hands - mostly due to suppliers who were behind schedule. Nothing major, but Paulo communicated about all of these in a timely fashion. We replaced all of our vinyl siding with James Hardie board. Also replaced several exterior windows. Paulo also replaced all of our old gutters. Everything was painted to order including old soffets and fascia. Someone touched up the drywall texturing around the new windows and then painted everything to match. The work was done efficiently. They paid attention to detail and fabricated nice trims around outlets and utility vents. My only gripe would be that they didn't leave the roof clean, and after the first rain, I found a lot of debris and nails that had blown down into the yard and driveway. Everybody on his crew was friendly and respectful. There was always at least one person on site who spoke perfect English."

"We had our siding and gutters replaced to include gutter guards as we have leaf season rather than fall. From start to finish this was the easiest renovation we've ever had done. We never had to make a phone call for any updates. The siding crew and gutter crew were awesome! They all worked hard and were very friendly and informative. The siding was completely finished in two days and the gutters in one. The project manager Jahleel was great with updates and checking on the crew's work. Super nice person!! We would enthusiastically recommend Home Genius for any exterior renovations."

"I had all the windows in my house replaced by Todd, and the experience was fantastic from start to finish. He was incredibly professional, showed great attention to detail, and made sure I was informed every step of the way. The quality of the work is top-notch — the windows look great and have already improved the feel of the home. I appreciated how responsive and reliable Todd was throughout the project. I wouldn’t hesitate to recommend him and would call him again for any future work."

"The siding the installers delivered was much darker than I expected it to be. Since I only had new siding installed on my West wall, it is much darker than the other three walls. Sadly, they did not have and could not have made anything lighter. I am sure someone makes a lighter blue siding, (since I had the lighter color installed over 20 years ago) but I have not found it."

"I decided to go with another product that was less expensive. Scott Williams was the sales/estimator. He was a pleasure to work with discussing my replacement window needs. He was punctual, friendly, and efficient. He answered all of my questions and offered additional information. I have no doubt that his company would have provided excellent customer service."

FAQs for vinyl siding install or completely replace projects in Longmont, CO

Insulated vinyl siding significantly improves your home's thermal resistance compared to standard vinyl products. The foam backing helps minimize heat transfer through your exterior walls, particularly addressing thermal bridging through wall studs. While the exact performance depends on the specific product and installation quality, this improvement can contribute to more consistent indoor temperatures and potentially reduced energy consumption. For maximum energy efficiency, insulated siding works best as part of a comprehensive insulation strategy rather than as a standalone solution.

The additional investment in insulated vinyl siding delivers multiple benefits that many homeowners find worthwhile. Beyond potential energy savings, the foam backing enhances durability against impacts and weather conditions. The insulation layer also helps reduce exterior noise transmission and creates a more solid feel than standard vinyl products. In regions with temperature extremes, the improved thermal performance can enhance comfort while potentially reducing heating and cooling expenses over time. The improved rigidity also helps maintain its appearance longer than standard vinyl options.

The longevity of insulated vinyl siding depends on several factors, including installation quality, local climate conditions, and maintenance practices. With proper care and regular cleaning, these products maintain their functionality and appearance for many years. Manufacturers provide warranty coverage that reflects their confidence in the product's durability. Environmental factors like sun exposure intensity and extreme temperature fluctuations can influence how the siding ages over time. Regular inspection and prompt attention to any damaged areas help maximize the system's effective lifespan.

The investment required for insulated vinyl siding on a home with 2,000 square feet of exterior wall surface falls between $8,000 and $24,000. This considerable range reflects variations in material quality, installation complexity, and regional pricing differences. Homes with multiple stories or intricate architectural details require more labor hours and specialized techniques, positioning them toward the higher end of the price spectrum. Obtaining multiple detailed estimates from qualified contractors provides the most accurate picture of costs for your specific property and preferences.
