“We worked with Elio Portillo and GHI Improvements on a full renovation of our old Victorian home, including a bump-out addition, brand new kitchen, 3.5 bathrooms, new master suite, refinished floors, finished basement…”

“I had an extra bedroom added to my house. It looked amazing when they were done. Looked like the bedroom always was a part of the house. They showed up on time every day that they came.”

What we build

Projects we take on in Harford County

Harford County is about an hour from our shop, so we schedule the projects that keep a crew on site for weeks, not an afternoon. If you are planning one of these, we are a fit:

Home additions

In-law suites, first-floor master bedrooms, sunrooms and two-story bump-outs that tie into the existing roof and siding.

Whole-home renovation

Kitchen, bathrooms, floors, trim and paint under one scope and one schedule, including older farmhouses and colonials.

Basement finishing

Full lower levels with a bathroom, a bedroom with egress, and a media or exercise room.

Kitchen remodeling

Full gut kitchens with new layout, cabinets, counters, tile and lighting.

Structural work

Removing a bearing wall, adding a beam, repairing framing found during a renovation.

Local proof

Where we work in Harford County

Bel Air, Fallston, Forest Hill, Abingdon, Bel Air South, Joppa, Edgewood, Aberdeen and Havre de Grace. Building permits are issued by the Harford County Department of Inspections, Licenses and Permits; we file and schedule the inspections. One of our reviews describes a full Victorian renovation with a bump-out addition, a new kitchen, three and a half bathrooms and a finished basement, the same mix of work you are reading about here.

Pricing

What a Harford County project costs

After the walkthrough you receive a written scope and price for the whole job. Because of the drive, we take Harford County projects from roughly $10,000 and up; additions and whole-home renovations are the usual fit. The estimate lists the schedule so you know when the crew arrives and when it leaves.

Good to know

Questions from Harford County homeowners

You are in Olney. Is Harford County too far?

No. It is about an hour up I-95 or Route 1. We book Harford County for multi-week projects so the crew is on site every working day, and the drive is ours, not yours.

Who handles the Harford County permit for an addition?

GHI does. An addition needs a building permit, zoning review for setbacks, and framing, electrical, plumbing and final inspections. We prepare the application and meet each inspector.

Will the addition match my house?

That is the job. We match roof pitch, siding, trim and window style so the new room reads as original. A homeowner review on this page says the new bedroom looked like it was always part of the house.

How is the price structured?

One written price for the scope you approve, with a payment schedule tied to milestones. Changes you request are priced in writing before they are built.

Do you do smaller jobs in Harford County?

Not usually. For a small repair in Bel Air you are better served by a local handyman than by waiting for our crew schedule.

Are you insured if something goes wrong?

Yes. GHI is a Maryland Home Improvement Commission licensee, which requires liability insurance, and your project is covered by the state Guaranty Fund.
