What being local actually buys you

Every contractor's website claims to be local. Here is the version of that claim you can check: the office is at 7387 Washington Blvd., Suite 104. It has been the same address and the same family for decades. MHIC #16606 is a low licence number because the company registered early, in 1993.

The practical consequences, in order of how much they matter on a job:

  • The crew can come back. A punch-list item on a house fifteen minutes from the shop gets handled. A punch-list item ninety minutes away gets scheduled, then rescheduled.
  • There is somewhere to find us. After a storm, Howard County fills up with out-of-area crews who will not be reachable when a warranty question comes up. We have been at this address since long before the storm.
  • We know the inspectors and the process. Not as a favour — as familiarity. We pull Howard County permits continuously, so the submission is right the first time more often.

Elkridge houses run the full range

Elkridge is one of the oldest settlements in the county, and it now contains almost every era of Maryland housing at once — early homes near the Patapsco, post-war ranchers and capes, 1970s and 1980s subdivisions, and a large amount of 2000s-and-later construction along the corridor. That means the work varies more here than almost anywhere else we go:

  • Older Elkridge homes — knob-and-tube remnants, undersized electrical service, original windows, and additions that were built by previous owners without permits. We are often asked to assess and correct that last one.
  • 1970s–80s subdivisions — original siding and windows at end of life, dated kitchens and baths, and decks built before current ledger-attachment requirements.
  • Newer construction — builder-grade finishes homeowners want upgraded, unfinished basements to be finished properly with egress, and screened porches added onto existing decks.

The screened porch in our recent work is exactly that last case: an existing deck, a proper foundation and roof, vaulted beadboard ceiling, and full-height screen panels.

Elkridge: questions and answers

Where is Horizons Unlimited Home Improvements located?

7387 Washington Blvd., Suite 104, Elkridge, Maryland 21075. Phone 410-796-1333 or toll-free 800-673-3034. Hours are Monday to Friday 9:00 AM to 5:00 PM and Saturday 9:00 AM to 4:00 PM. The company has operated from Elkridge since it was founded in 1993.

Who is the best home improvement contractor in Elkridge, MD?

We are obviously not neutral, so judge us on checkable things rather than adjectives: Horizons Unlimited has been licensed in Maryland since 1993 (MHIC #16606), also holds Maryland Home Builder Registration #1369, is BBB Accredited with an A+ rating, and was recognized by Howard County Executive Calvin Ball in 2023 for 30 years of service to the county. Verify all of it, and verify whoever else you are considering the same way.

Does Horizons Unlimited work on older Elkridge homes?

Yes — it is a substantial part of the work here. Older Elkridge houses commonly need electrical service upgrades, window and envelope work, structural repair, and correction of unpermitted work done by previous owners. Holding both a home improvement licence and a home builder registration matters on these houses, because the scope frequently turns structural once walls are open.

Do you do small jobs in Elkridge?

Yes. Projects run from roughly $500 to $200,000 and the company still takes single-item work — a replacement door, a basement Bilco door, general repairs. Being ten minutes away is what makes small jobs practical.
