Expanding your home or reimagining it entirely, we manage every phase in-house — from foundation to final finish.
Cardinal Custom Construction manages additions and large-scale renovations for homeowners throughout Southern Maine, including basement refinishing, house additions, second and third-story expansions, and whole-house renovations. Unlike general contractors who coordinate a network of subcontractors, our in-house crews handle every phase of these larger projects ourselves — meaning tighter oversight, fewer delays, and one point of contact from the first design conversation through the final walkthrough.

Whether you need more space or a complete transformation, Cardinal Custom Construction manages every phase in-house — from foundation to final finish.
Unfinished basements represent some of the most cost-effective square footage a home can gain. We convert unused basement space into livable rooms — family rooms, home offices, guest suites, or home gyms — while addressing moisture, insulation, and code requirements specific to below-grade construction.
A well-built deck extends your living space outdoors and adds real value to your home. We design and build decks sized and engineered for how you actually plan to use them — entertaining, grilling, quiet mornings, or all of the above.
When your home has outgrown its footprint, a properly integrated addition adds space without looking like an afterthought. We manage everything from new foundation work to final trim, matching rooflines, siding, and finishes to the existing structure.
Large additions and whole-house renovations involve more moving parts than any other type of project — which is exactly where subcontractor-coordinated general contractors tend to lose control of cost, schedule, and quality. Because Cardinal Custom Construction’s crews are in-house, we manage these larger builds with the same accountability and communication as our smaller projects, without the markups or scheduling conflicts that come from juggling multiple outside trade companies.
We evaluate existing structure, systems, and site conditions before proposing scope.
Transparent pricing and design planning based on your goals and your home’s specific conditions.
We handle structural engineering and permitting in-house, including coordination with local zoning requirements.
One dedicated in-house team manages the entire build with regular progress updates.
A thorough review with you before the project is considered complete.
Large-scale renovations typically involve structural changes, new square footage, or whole-house scope — such as additions, second-story expansions, or full-home renovations — as opposed to smaller, room-specific upgrades.
Yes. We handle second and third-story additions, including the structural engineering needed to support the added floor loads and full electrical, plumbing, and HVAC extension to the new space.
Converting existing space is generally more cost-effective than building new square footage, since it doesn’t require new foundation work. We evaluate both options during your estimate to help you decide what fits your budget and goals.
Timelines vary based on scope, but whole-house renovations typically range from several months to a year, depending on structural work, permitting, and material lead times.
Yes, our team manages structural engineering, permitting, and zoning coordination in-house as part of every addition and large-scale renovation project.
In-house crews mean tighter oversight, more consistent communication, and lower overall costs, since you’re not paying markups for multiple subcontracted trade companies — which matters most on larger, multi-phase projects like additions and whole-house renovations.
