Andover homeowners invest in outdoor space because the lots support it — many homes in West Andover, Haggetts, and South Andover sit on half-acre or larger parcels with established landscaping and mature tree cover. That means decks that need to account for shade, grading, tree root systems, and drainage patterns that change season to season. A deck built without understanding the lot it sits on won’t last.

Andover homes range from colonials on compact lots near the town center to larger properties in West Andover and off High Plain Road with sloped yards and wooded borders. The deck design has to match how you actually plan to use the space — and how the lot allows it. That’s where every project starts.
Understanding how you plan to use the deck. Before any measurements, material choices, or design work, we sit down and talk through what you want — entertaining, a quiet sitting area, outdoor kitchen, hot tub, usable space underneath, a play area the kids will grow out of. The layout, framing specs, and material selection all flow from that conversation. We don’t start with a template — we start with your goals for the space.
Most composite deck projects in Andover range from $30,000 to $80,000+ depending on size, material tier, elevation, and custom features. Larger multi-level decks, outdoor kitchens, hot tub platforms, and under-deck drainage systems push toward the higher end. Andover’s larger homes often call for decks that match the scale of the property. We provide a detailed written estimate after an on-site consultation.
Trex, TimberTech, and Azek — all premium composite and PVC decking lines. We’re certified installers for both Trex and TimberTech. Each brand has multiple tiers with different price points, textures, and color options. We’ll walk you through samples and help you choose based on your budget, aesthetic preference, and how exposed the deck will be to sun and weather.
No. We build exclusively with composite and PVC decking materials. Pressure-treated lumber warps, cracks, splinters, and requires annual staining and sealing — especially in Andover’s freeze-thaw climate where shaded backyards accelerate moisture damage. Composite decking holds its shape, resists moisture, and doesn’t require annual maintenance. The framing underneath is structural lumber engineered to code, but every surface you walk on and look at is composite.
Yes. The Town of Andover Building Division requires a building permit for all new deck construction and most major deck modifications. A certified plot plan showing setbacks and property lines is required. We handle all permit applications, coordinate inspections at footing, framing, and final stages, and ensure everything meets current Massachusetts building code.
Absolutely — and Andover has a lot of them, particularly in West Andover and in the neighborhoods near Harold Parker State Forest. Sloped lots require engineered substructures with proper pier depth, stepped footings, and sometimes retaining elements. The elevation changes often create opportunities for multi-level decks and usable under-deck space that you wouldn’t get on a flat lot.
