Post-Completion Care & Warranty Process

Each project starts by understanding your goals and documenting your home, then developing early design concepts that guide scope, feasibility, and budget. This step involves:

In-depth consultation to clarify vision, needs, and budget
Full documentation of existing home conditions
Preliminary sketches, floor plans, and elevations
Zoning and code review for feasibility
Initial cost estimate for early budget clarity
Approval of concept and budget before advancing to design development

Your initial concepts become fully developed plans, complete with detailed specifications, material selections, and final budgeting.

Refined floor plans, elevations, and detailed drawings
Selection of finishes, fixtures, materials, and appliances
Subcontractor quoting for accurate project pricing
Finalized fixed-cost budget
Signing of the construction contract
Preparation of permit-ready drawings

Once permits are secured and plans are finalized, our team brings your design to life with precision, communication, and proven craftsmanship.

Pre-construction staff meeting and project kickoff
Weekly on-site meetings with your Project Manager
Updates and ongoing communication
Construction completed according to approved plans
Completion walk-through with your team
Final job checklist to make sure every detail is addressed

About Hopkins & Porter

Since 1977, Hopkins & Porter has earned a reputation for thoughtful design, meticulous craftsmanship, and a service-minded approach to remodeling. What began as a small team has evolved into a full-service design-build firm with project coordinators, and skilled craftsmen. Many have been with us for over 15 years.

Founded by Guy Semmes and Mike Denker, the company was shaped by a passion for preserving and enhancing residential architecture across the Northwest DC area. Today, under the leadership of Ray Hornsby, we continue to uphold the belief that remodeling is a service, not a product. Every interaction, every detail, and every decision reflects our core value: “It’s the way we care.”

Frequently Asked Questions

What makes Hopkins & Porter different from other remodeling companies?

We specialize in large-scale renovations, providing a white glove design-build process. We also provide a rare 5-year Active warranty. Our experienced team delivers professional, transparent communication, crystal-clear budgeting, and a service-first approach, backed by over 40 years of proven results.

What types of projects does Hopkins & Porter handle?

We manage custom home additions, whole-home remodels, kitchen and bathroom renovations, aging-in-place updates, historic renovations, ADUs, and complete home transformations. Our handyman division also provides long-term home maintenance and minor repairs.

How does the design-build process benefit homeowners?

The design-build process provides a more streamlined experience with a single team managing all aspects of design, budgeting, permits, and construction. This approach helps to reduce delays, avoid lapses in communication, and produce more cohesive results - while giving homeowners greater cost control and confidence in the project.

How long does a remodeling project typically take?

Timelines can vary greatly by project scope, complexity, and the age of the home. Whole-home remodels and major additions generally take several months from design through completion. When you work with a design-build firm, they should provide a timeline to complete the project, keeping you updated every step of the way.

Do remodeling projects require permits in DC or Maryland?

Most structural updates, additions, and major remodels require permits. When you work with a design-build firm, they will manage all permitting, inspections, and code compliance, making sure your project meets local regulations and maintains architectural integrity.

Do you provide support after the project is completed?

Yes. Our extended 5-year Active warranty, scheduled walk-throughs, and dedicated handyman division provide ongoing care and long-term peace of mind.

Our warranties include:

9-month walk-through to address settling items
18-month walk-through for continued care
