We review how you want to improve the space, then look at access, structure, measurements, drainage, and existing conditions.

We help compare layouts, materials, finishes, and customization options that improve comfort, curb appeal, and daily use.

Once the plan is set, we organize the scope, selections, permit details when needed, and material ordering.

Our team focuses on workmanship, clean finish details, respectful communication, cleanup, and final walkthrough.

Working with one Outdoor Living Contractor in Portsmouth keeps the design, scope, permits, materials, and construction details coordinated from the initial site review through the final walkthrough.


Yes. ModExt Construction serves homeowners in Portsmouth for custom decks, porches, sunrooms, screen rooms, porch and patio enclosures, patio covers, pergolas, pavilions, louvered roofs, and related outdoor-living improvements. Service availability is confirmed using the project address and scope.
For Portsmouth homes, material selection should account for humidity, heavy rain, sun exposure, insects, and—in properties closer to tidal water—salt-air and wind exposure. ModExt may recommend capped composite or PVC decking, corrosion-resistant fasteners, properly flashed roof systems, moisture-tolerant trim, and finishes selected for the actual site.
Portsmouth requires building permit applications for new structures, additions, and alterations. Zoning approval may also be required before construction, depending on the location and scope.
