What areas does Knox’s Construction serve?

Do you offer siding installation and repair?
Yes. In addition to roofing, we provide professional siding replacement and repair using high-quality products such as Mastic and James Hardie® siding. New siding improves curb appeal, energy efficiency, and protection against the elements.
Why are gutters important for my home?
Properly functioning gutters and downspouts direct rainwater away from your home’s foundation, roof, and landscaping. This helps prevent water damage, basement flooding, erosion, and costly structural repairs. We offer gutter installation, seamless gutters, gutter cleaning, repairs, and gutter protection systems.
What are the benefits of seamless gutters?
Seamless gutters have fewer joints than traditional sectional gutters, reducing the chance of leaks and clogs. They provide improved durability, require less maintenance, and offer a cleaner appearance that complements your home’s exterior.
Why are soffit and fascia important?
Soffit and fascia help protect your roof and attic by improving ventilation, preventing moisture buildup, supporting your gutter system, and keeping pests out. Well-maintained soffit and fascia also enhance the appearance and longevity of your home’s exterior.
How can I get a free estimate for my roofing or exterior project?
Scheduling a free estimate is easy. Contact Knox’s Construction to arrange an inspection of your roof, siding, gutters, or exterior. We’ll evaluate your home’s needs, explain your options, and provide a detailed, no-obligation estimate so you can make an informed decision.
