Basement Drywall in Meridian, Idaho
Meridian Quality Drywall hangs basement drywall in Meridian on former farm ground where the first question is moisture, not texture. Ada County basements sit in irrigation country. Gypsum goes on furring or a stud wall after the space is dry enough to board. We do not trap damp concrete behind paper-faced gypsum.
Call (208) 382-8431 with the basement size, whether a bath is in the plan, and joist spacing on the lid. We quote after we know the moisture picture.

Basement Drywall Options for Meridian Properties
Standard hang on furred walls
A stud wall or furring off the concrete, then 1/2-inch on the interiors. Electrical and plumbing have to be in the cavity first. We hang after those inspections, same as upstairs.
Moisture-resistant on bath walls
A basement bath still gets MR board outside the shower and cement board in the surround. Cooler air does not change the wet zone. It only slows the mud.
Type X under a garage
Some south Meridian plans put living space next to or under a garage plane. We hang the rated lid or wall the spec names, then finish the basement rooms to the paint level you want.
Cold-wall gap or channel
A gap, hat channel, or insulated stud wall keeps gypsum off the concrete. We do not skip this to save a day. Paper-faced board on damp concrete is a peel later.
How We Handle Basement Drywall in Meridian
- Ask about water. Efflorescence, a past flood, and a wet carpet are stops. The hang waits.
- Confirm furring, vapor detail, and that mechanicals are inspected.
- Hang the lid first on 24-inch joists with 5/8-inch, then the walls.
- Tape in setting compound. Basement air is slower. We give coats real dry time.
- Texture to match upstairs or leave Level 4 smooth if that is the plan.
Materials and Methods
ASTM C1396 1/2-inch on dry interior basement walls. 5/8-inch on lids at 24-inch centers. Moisture-resistant board in basement baths. Cement board in showers. Paper tape. Hot mud beds the tape. Ready-mix for later coats. A lift for low lids. Hat channel or wood furring as the wall design requires. We are not the waterproofing trade. We hang after that trade has done its work. GA-216 still governs the hang. GA-214 governs the finish. Type X only where the assembly is rated.
Former farm ground under Meridian still carries irrigation laterals on some lots. A basement that weeps in June is not a texture problem. We want the water story before we close the walls. Efflorescence on the concrete is a stop.
Low lids make hanging slower, not cheaper per sheet. A lift still helps. Box cuts for basement windows and bulkheads around ducts are the extra labor. We quote those as part of the basement, not as a surprise on day two.
What Basement Drywall Costs in Meridian
Fixr lists a typical basement hang nationally around 1,380 to 1,500 dollars on their sample size, with hung-and-finished board still in the one-fifty to three-fifty per square foot band. Angi and HomeAdvisor use the same installed band for standard gypsum, with moisture-resistant board a little higher. Height is usually lower downstairs, which cuts wall square footage, but MR board, Type X, and slow dry time add it back. We quote the basement as its own hang.
Bulkheads around ducts are extra cuts and extra bead. They are also where people bump heads, so the bead has to be solid. We hang the bulkhead as its own little room: lid, sides, tape, texture. A basement quote that forgets bulkheads is short.
Egress windows and window wells mean more returns and more corner bead in a small field. We cut those openings tight. A sloppy basement window return is a crack and a draft. Tight gypsum here is worth the extra hour.
Stairs into a basement are a hang of their own: angled stringers, a low head, and a lid that meets the first-floor joists. We hang the stair walls after the treads are in or we protect the treads. Mud on new treads is a fight with the carpenter.
If the basement will be a bedroom, egress and smoke openings are part of the lid and wall layout. We cut those openings to the box. We do not guess later. Say the room use when you call so the hang matches the plan.
Irrigation laterals and cold concrete
South Meridian and west Meridian sit on former irrigated farm ground. Laterals run in spring. A basement that feels damp in May is not ready for gypsum. We hang on furring or a framed wall, not on the concrete face.
Lids on 24-inch joists take 5/8-inch. Baths take MR board. A legal bedroom needs the window and the alarm more than it needs fancy texture, but we still match upstairs knockdown if that is the house.
January cellars are cold. Mud does not dry. Heat in the rooms we coat, or a longer schedule.
Call (208) 382-8431 with whether the basement is framed and whether water has been on the floor.
Questions
Should a Meridian basement get regular board?
On dry, furred interior walls, 1/2-inch is common. Lids on 24-inch joists take 5/8-inch. Baths take moisture-resistant board. We do not hang on a wet concrete face. Name the town and the job when you call.
Do you hang on the concrete?
No. We hang on furring or a framed wall with a gap or a channel so the board is not against damp concrete. Direct bond on a basement wall is a moisture trap. Name the town and the job when you call.
What about a basement under a garage?
The assembly above may be Type X. We follow the rated lid spec, then finish the basement as living space. Name the town and the job when you call. We quote before work starts.
Will knockdown match the upstairs?
We can spray the same knockdown. Basement air is cooler and damper, so dry time is longer. We do not rush coats in a cold cellar in January. We hang after those inspections, same as upstairs. Name the town and the job when you call.
When do irrigation laterals matter?
Spring, on former farm ground in south and west Meridian. The water table comes up. We meter the foundation before we hang. Weeping concrete stops the job. Name the town and the job when you call. Name the town and the job when you call. We quote before work starts.
Do basement bedrooms need more than board?
Egress and smoke alarms are not drywall, but they decide if the room is legal. We hang after those are in the plan. Name the town and the job when you call. Name the town and the job when you call. We quote before work starts.
