Services we build in Forest Hill
Custom decks in Forest Hill
Forest Hill sits on the elevated western side of Harford County, and many of the lots we work on drop off sharply behind the house. That means multi-level decks, longer stair runs, and taller structural posts. We have built dozens of decks across the Forest Greens and Atlanta Hall neighborhoods, and we design around the grade rather than fighting it. Composite railings, hidden fasteners, and post-tensioned framing are standard on the Forest Hill decks we build.

"Custom Design & Build did a superb job on restoring my deck. The finished product exceeded my expectations. I am considering Custom Design & Build for future remodeling projects on my home."
Custom pergolas in Forest Hill
Forest Hill's elevated terrain can change how a pergola relates to the deck, house, and prevailing weather. Near Forest Greens, Atlanta Hall, Eden Mill, and the roads toward Rocks State Park, we evaluate grade and exposure before deciding whether the structure should be freestanding or connected to an existing outdoor area. We build traditional wood pergolas and certified Azenco aluminum systems. Our team handles the Harford County permit, any applicable HOA review, and installation with our own crews from our nearby Fallston office.

Sunrooms in Forest Hill
Forest Hill's changing grade makes the structure below a sunroom as important as the enclosure above it. In Forest Greens, Atlanta Hall, and properties toward Eden Mill or Rocks State Park, we evaluate support height, stairs, drainage, and the roof connection before design begins. We are an authorized Sunspace dealer with three-season and four-season systems. Our own crews build the complete project, and we coordinate Harford County permitting and inspections so responsibility does not shift between separate companies.

Retractable awnings in Forest Hill
Add on-demand shade to your Forest Hill deck or patio with a motorized Alutech SunShield retractable awning. As an authorized Alutech dealer, we install premium Sunbrella awnings with LED-lit arms, remote operation, and optional wind and sun sensors for Forest Hill homeowners, usually in a single day. Extend it when you want shade, retract it when you want full sun.
