You bought in Columbia or Ellicott City for the schools and the commute, and now the kitchen is too small and the basement is still concrete. You get one written price for the whole job and a crew that drives in from Olney, about 25 minutes away, and stays until it passes inspection.
Every review below is a public Google review of GHI Improvements.
“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…”
Melissa Joy · Oct 2025“Elio and his team did a great job finishing my basement. They added custom shelves and a closet and did everything asked of them and more. I would highly recommend and will use them again.”
Timothy Harwood · Jun 2024“They do what they say and deliver on the timeline they estimated. Elio is very responsive and looks to add value and help you through difficult design issues. Great company for any type of home improvement or home construction.”
Google reviewer · Aug 2025Most Howard County calls are about homes built between 1970 and 1995, when Columbia was filling in. They have small closed kitchens, long unfinished basements and one bathroom too few. These are the jobs we price most often:
Opening the wall between the kitchen and the family room, new cabinets and counters, island with seating, lighting on a new circuit.
Framing, insulation, an egress window where the county requires one, a full bathroom and a storage room that is actually finished.
A second full bath for a growing family, or a hall bath turned into a walk-in shower you can age into.
Family rooms, first-floor bedrooms and bump-outs that match the roofline and siding of the house.
Floors, trim, paint, doors and a kitchen in one scope, so the house feels new at once instead of in pieces.
Columbia, including Wilde Lake, Harper's Choice, Owen Brown, Long Reach, River Hill and Dorsey's Search, plus Ellicott City, Clarksville, Fulton, Elkridge and the Howard County side of Laurel. Permits go through the Howard County Department of Inspections, Licenses and Permits; we file them and schedule the inspections. The reviews on this page are public Google reviews of GHI work in Maryland, including a Victorian renovation with a bump-out addition and several finished basements.




You get a written scope and price after the walkthrough, line by line, so you can compare it with other bids. No vague allowances that grow later. Most Howard County projects we take on are remodels and additions from roughly $10,000 up; for a small repair we will point you to a handyman so you are not waiting on our crew.
We visit, measure and listen to what you want from the space.
A clear scope and price in writing. No vague allowances.
GHI files with Howard County Department of Inspections, Licenses and Permits and schedules the inspections. One crew, one point of contact.
We finish the punch list, clean up and hand over a space that passes inspection.
Three quick questions, then a call back to set your walkthrough, usually the same business day.
Yes. Columbia is about 25 minutes from our shop in Olney by Route 108 or Route 32, Ellicott City about 30. The crew comes every working day until the job is done; nobody is dispatched from a call center.
We do. Additions, basements with bedrooms or bathrooms, and any structural change need a Howard County building permit. We file the application, meet the inspectors and hand you the final approval.
If the basement has a bedroom, yes, and the county inspects it. We cut and install the well and window as part of the basement scope so it is in the price from the start.
A full kitchen with layout changes usually runs four to eight weeks on site once cabinets are in hand. Your written estimate includes the schedule.
Yes. Our Google profile has more than 200 photos of real job sites, and the photos on this page are from GHI projects, not stock.
We coordinate the licensed trades inside the one scope, so you have one price and one person to call.
