Rockville’s Crack Repair Specialists, Not a Paint-Over Job
A crack means something moved. We find out what moved before we tape it. Seam cracks, stress cracks above doors and windows, corner cracks and nail pops all have different causes, and each gets its own fix.
We cut out loose tape, fasten loose board with screws and bed new tape in setting compound. Spackle on its own fills the gap for a season, then the crack opens again.
Cracks are the most common call we get as a local drywall repair company in Rockville.
Four Kinds of Cracks We See in Rockville Homes
Seam cracks
Straight lines along drywall joints, where the tape has let go.
Stress cracks
Diagonal cracks from the corners of doors and windows, caused by the house settling.
Corner cracks
Splits in inside corners, where two walls or a wall and ceiling meet.
Hairline cracks in plaster
Fine, spidery lines in older homes with plaster walls.
Wide, growing or stair-step cracks can point to a structural issue. If we see one, we tell you and suggest a structural engineer before we patch.

The Rockville Problem: Why Cracks Come Back Every Winter
Humid summers and cold, dry winters make wood framing swell and shrink every year.
- October to November: The heat comes on, framing dries, and nail pops and seam cracks show up.
- December to February: Cracks along outside walls widen in the coldest weeks.
- March to May: Spring rain and thaw can shift a foundation a little, opening stress cracks at doors and windows.
- June to September: Humid air softens compound, and weak tape lifts.
Cracks fixed with screws, new tape and setting compound hold through these swings far better than a skim of spackle.
Cracks We Repair and How We Fix Each One
The shape and spot of a crack tell us why it formed. That decides the fix. These are the crack types Rockville homeowners call us about most.
Hairline Crack Repair
Thin, spidery lines often show up on walls after the first cold snap. Many are in the paint or top coat only. We open the crack slightly so compound can grip, fill it with setting compound and sand it flat. If the line runs along a seam, we treat it as a seam crack instead, because filler alone won’t hold there.
Settling and Stress Crack Repair
Diagonal cracks that run from the corners of doors and windows come from the house settling and framing moving. They are the most common cracks in Rockville homes built in the 1950s and 1960s. We screw the board tight to the framing, cut a V along the crack, bed tape across it and finish wide so small movement doesn’t reopen it.
Drywall Seam and Joint Crack Repair
Straight cracks along the joints between sheets mean the tape has let go. We cut out the loose tape, clean the joint and bed new paper tape in setting compound. Butt joints, where two cut ends meet, get a wider finish so the repair stays flat and doesn’t show a ridge.
Corner Crack Repair
Inside corners, where two walls or a wall and ceiling meet, crack when framing moves. We remove the cracked tape, bed new tape folded into the corner and finish both sides. Damage on outside corners is usually the metal or vinyl strip underneath, which we fix through corner bead repair.
Large Cracks in Walls
A crack wider than about 1/4 inch, one that keeps growing, or a stair-step crack in brick or block should be checked by a pro. Mark both ends with a pencil and a date. If it grows past the marks in a few weeks, call a structural engineer before any patching. We only repair cracks once the cause has stopped moving.
Ceiling Crack Repair
Ceiling cracks often follow joists or run along outside walls. The fix is the same as on walls, but done overhead with the room covered. Cracks with sagging or stains around them point to other trouble, so we cover them in ceiling drywall repair or water damage repair.
Plaster Crack Repair
Older homes in the West End and East Rockville have plaster walls that crack in fine webs. We use a bonding agent, mesh tape across the crack and setting compound made to grip plaster. The goal is a flat wall that keeps its old character.
Crack Repair and Finishing
The last step decides whether anyone can see the repair. We feather the compound wide, sand it smooth and match the texture around it with the same care as our texture matching work. The wall is primed and ready for paint.
Our 5-Step Drywall Crack Repair Process
Find the cause
We look at the pattern, the location and the age of the house to see what moved.
Open and clean
Loose tape and crumbling compound are cut out so the new work bonds to solid material.
Fasten
Loose board is screwed to the framing, and nail pops are set with screws beside them.
Tape and bed
New tape goes into setting compound, which hardens by chemical reaction and shrinks less.
Finish, texture and prime
Thin coats are feathered wide, the texture is matched and the repair is primed.
What’s included in a crack repair visit?

Crack Repair Answers
Are drywall cracks a sign of structural problems?
Most are not. Hairline seam cracks and nail pops come from normal framing movement. Cracks wider than about 1/4 inch, cracks that keep growing, or stair-step cracks in masonry are worth showing to a structural engineer.
Why does my crack keep coming back?
Usually because it was only filled, not re-taped. The board or tape is still moving underneath. Re-fastening the board and bedding new tape stops that.
Got Questions About Crack Repair?
What causes nail pops?
Wood framing shrinks as it dries and pushes nails back out. We set drywall screws next to them and spot-finish.
Do you use mesh or paper tape?
Both. Paper tape in setting compound for most seams and corners, and mesh for some patch edges. We pick what holds best for each crack.
Can you repair cracks in plaster walls?
Yes. We use bonding agents and setting compound made to grip plaster.
How long does crack repair take?
Most crack repairs take one or two visits, because each coat needs to dry.
Will the crack show through paint?
Not when it’s feathered wide, textured to match and primed.
Do crack repair sprays or kits work?
Sprays and elastic fillers can hide a hairline crack in the paint for a while. On a seam or a stress crack, they don’t stop the movement underneath, so the crack returns. Re-taping with setting compound lasts much longer.
What’s the best tape for ceiling cracks?
Paper tape bedded in setting compound is the strongest choice for most ceiling seams. Mesh tape works for small patch edges, but on a long ceiling seam it is more likely to crack again.
More answers are on our drywall FAQ page.
If the repaired texture shows once the wall is painted, we come back and redo it.
