"Start to finish, excellent service and value delivered. Crew & team were extremely professional, great communicators, always went the extra step to ensure the project was done exactly as it was requested. We moved into a new office space and originally just wanted some touch-ups, they transformed the space into something we didn't think was possible, all while meeting our tight deadlines. Wouldn't look anywhere else for any future commercial or residential work to be done."

"Having lived in our house for 32 years, we needed a lot of work done before putting it on the market. Torin was a consummate professional from start to finish. He was responsive and flexible. He and his crew painted all the rooms on our first and second floors; replaced toilets, windows, doors, railings, and light fixtures; refinished tubs; repaired siding damage, fascia boards, rot, and ceiling damage; installed insulation; and did additional work to the interior and exterior of our garage. He brought in electricians and plumbers as needed. Torin completed all work in a timely manner, and we always knew where we were in the process. I could not recommend him more highly!"

FAQs for exterior home or structure paint or stain projects in Merrimack, NH

For aluminum siding, go with a high-quality 100% acrylic exterior paint. Start with an oil-based primer to ensure the finish adheres and shields the metal from oxidation and moisture. The primer seals the surface and provides the acrylic with a surface to grip. Skip latex primers or paints—their reaction with aluminum can trap bubbles and cause early peeling.

How long will painted aluminum siding last?

A well-done paint job on aluminum siding can last around 15 years, making the upfront effort worthwhile. Longevity hinges on solid prep: thoroughly cleaning the surface to remove chalky residue, dirt, and mildew so the new paint can adhere properly. It’s also important to paint when temperatures are between 50°F and 80°F, as extreme heat or cold can affect drying and adhesion. Steer clear of rainy days—moisture under the paint weakens adhesion and speeds up peeling or fading, which can significantly shorten the lifespan of your fresh coat.

Plan on repainting when the finish starts fading or leaves a chalky, white residue on your hand. Check the siding each year; if there’s a powdery residue on your palm, it indicates oxidation is underway on your siding. A fresh coat of paint stops peeling before it starts, boosts curb appeal, and keeps the metal protected.

Spray painting aluminum siding offers significant benefits compared to other application styles. Spray painting delivers even coverage, rapid application, and enhanced adhesion compared to traditional painting methods. This technique ensures every surface is evenly coated, minimizes labor time, and provides a sleek, professional finish that withstands weather and oxidation for lasting results.

The return on investment for aluminum siding is 70%. For example, a $10,000 aluminum siding installation will add $7,000 to your home’s resale value. Regional housing markets, the quality of siding materials, and ongoing upkeep—including repainting and repairs—influence final ROI. Investing in professional installation and regular maintenance ensures you recoup a significant portion of your siding costs when it’s time to sell.

Several materials can replace aluminum siding, each offering unique trade-offs. Vinyl siding requires minimal upkeep and resists fading, lasting up to 30 years. Wood siding provides classic warmth but demands regular painting or sealing. Fiber cement and composite siding offer exceptional durability and design flexibility, requiring minimal maintenance. Brick veneer and stucco create premium, long-lasting exteriors, but they come with higher upfront costs and increased installation complexity.
