North Potomac sits in Montgomery County, Maryland, which makes it a different proposition from most of our service area — not because the houses are unusual, but because the law is. Maryland regulates home improvement contractors far more tightly than Virginia does, and that gives you protections worth knowing about before you take a single quote.
The housing here is mostly 1970s through 1990s: large colonials and split-levels on generous, heavily wooded lots, with a lot of cedar and T-111 plywood siding still in place. So this page covers two things — how to check who you are hiring, and what that siding actually needs.
Before you compare prices, check the license
In Maryland a home improvement contractor must hold a license from the Maryland Home Improvement Commission. This is not a trade body or a formality — working without one is a criminal offense, and the state keeps a public register you can search in about a minute.
Our MHIC license
[MHIC #00000]
Don't take our word for it. Look it up on the Commission's register and confirm it's current before you sign anything — with us or with anyone else.
How to check any contractor in 60 seconds
- Ask for the MHIC number. If there isn't one, stop there.
- Search it on the Maryland Home Improvement Commission's online license register.
- Confirm the name matches and the status is current — not lapsed, not suspended.
The Guaranty Fund — and why the license matters
Maryland runs a Home Improvement Guaranty Fund, financed by assessments on licensed contractors. If a licensed contractor does your job in an unworkmanlike, incomplete or incorrect way, or abandons it, you can claim against that fund for the cost of putting it right.
| Topic | Details |
|---|---|
| Maximum Claim | $30,000 per claimant, or the amount you paid the contractor — whichever is less. |
| Time to File | You have three years from discovering the loss to file a claim. |
| Maximum Deposit | No more than one-third of the contract price. A painter asking for half up front is outside the Commission's advice. |
| You Are Entitled To | A written contract, a current certificate of liability insurance, lead paint accreditation where required, and references. |
| If the Contractor Is Unlicensed | There is no protection from the Guaranty Fund at all. In the Commission's own words, the cheapest quote from an unlicensed painter is the same quote with the safety net removed. |

T-111 and cedar: the 1970s and 80s siding problem
A great deal of North Potomac was built when T-111 was the standard exterior. Grooved plywood panel siding, looks like board-and-batten from the street, and when maintained it lasts for decades. When it is not, it fails in a very particular sequence.
- The bottom edge goes first. Panel edges wick moisture. Too close to grade, buried behind a flower bed, or never sealed — it swells, delaminates and comes apart in layers.
- Then the grooves. Water sits in the vertical grooves, and on thinly painted panels the coating fails there before anywhere else.
- Then the joints. Panel-to-panel seams and trim transitions open up as the caulk behind them fails.
Which means this is a prep-heavy substrate, and anyone quoting it as a straight wash-and-two-coats has not looked at it properly. We probe the bottom edges, replace delaminated panels rather than filling them, seal every cut edge, re-caulk the joints and prime bare plywood before topcoating. Done that way, T-111 takes paint well and holds it.
Cedar is the other survivor here. It moves, it bleeds tannin through light colors unless it is blocked properly, and it needs a stain-blocking primer rather than a general-purpose one. Weathered gray cedar needs the loose fiber cleaned off first, or the new coating takes the failing surface with it.
What the tree canopy does to a paint job
North Potomac lots are wooded, and mature trees are the main reason exteriors here fail unevenly. Three separate mechanisms, worth separating because the fix differs for each.
Retained moisture
Shaded elevations dry slowly, and slow-drying siding grows mildew. Mildew under a new coat will grow through it — the cleaning has to actually kill it, not just rinse the surface.
Contact damage
Limbs resting on or brushing siding abrade the coating, then hold water against the bare spot. We flag anything touching the house at the estimate; the honest advice is usually to cut it back before we start.
Debris and overflow
Blocked gutters overflow down the fascia and behind the siding. Paint over that will fail, exactly where the water runs. Clearing them is part of the prep conversation, not an upsell.
Expect north and east elevations under canopy to need attention before the sunny sides. That is not a defect in the work — and any contractor promising identical performance on all four elevations of a wooded lot is overselling.
Interiors in an 80s and 90s colonial
The opposite of the open-plan houses being built further out: separate rooms, defined doorways, and a specific set of dated finishes a repaint can address far more cheaply than a remodel.
Honey oak trim and banisters
Painting oak properly means degreasing, sanding, a bonding primer — and accepting that the open grain will read slightly through the finish unless it is grain-filled. We will show you which you are getting before we start.
Textured and popcorn ceilings
Can be painted, and painting is far less disruptive than removal — but sprayed texture drinks material and cannot be rolled hard without pulling texture off.
Compartmentalized rooms
Actually an advantage. You can change color room by room without the boundary problem open-plan houses have, and you can phase the work over time.
Wallpaper
Still widespread in this vintage, especially powder rooms and dining rooms. Removal and proper wall preparation is usually the right answer.
