The kids want their own rooms, the office lives on the dining table, and over the hall ceiling sits a whole empty floor. Our carpenters work out whether that Harrison City attic can hold a room, then build the room out, floor to ceiling.
Harrison City Attics
Most 15636 houses were built between the Reagan years and the late 2000s, over a third count four bedrooms, and close to 30 percent of households include kids. That decides what an attic here can become.
Seventy percent of Harrison City's homes date from 1980 to 2009. Where a roof is built from engineered trusses, the web of diagonal boards that fills the attic cannot be cut out without a new engineered design, and that settles what is possible.
We climb up before anything else and tell you which you have. Rafters usually leave room to work; trusses may need an engineer's redesign, or point us to a better spot for the room, such as over the garage or downstairs.
What we find up thereEven with four bedrooms, which over a third of 15636 homes have, a house can run short. When a teenager wants a door that closes, the attic is often the last space the house has left without building an addition.
The floor is framed for a bedroom's load, the room laid out so most of it clears seven feet, an egress window framed into the gable, and a smoke alarm wired in. Closets tuck into the low space at the eaves.
Attic bedrooms and suitesClose to 30 percent of Harrison City households include children. Parents who are tired of toys in the living room want a bonus room upstairs that can take running, jumping and the occasional dropped bin of blocks.
We stiffen the floor so it does not bounce, lay carpet or wood over a quiet subfloor, and turn the knee walls into cubbies and drawers. Sound insulation between the joists keeps the noise from landing on the rooms below.
Playrooms and bonus roomsWestmoreland County searches for attic ladders and attic stairs run every month. A pull-down ladder works for boxes, but nobody wants to carry a laundry basket or a sleeping child up one, and a real room needs a real stair.
The stair usually comes down into a closet or the end of a hall; we frame that opening and build the run at least 36 inches wide with code risers, treads and a handrail. Headroom over every step clears six foot eight.
Stairs and accessAttic insulation searches across the county nearly triple from summer into winter, and mini splits draw about 140 searches a month. An attic room has the roof as its ceiling, so it feels every hot afternoon and every cold night first.
Insulation and air sealing move up to the roofline from the old attic floor, a vent channel runs beneath the roof sheathing, and usually add a ductless mini-split, since the furnace ducts rarely reach the attic level well.
Insulation and ventilationA roof that looks roomy from the hallway hatch can turn out to have standing room only along a narrow strip down the middle. Dormers draw steady searches in the county from owners who have hit exactly that wall.
We measure first, then frame a dormer into the roof where it gains the most floor at full height, flash it into the existing shingles, and size its rafters for the snow that sits on a Harrison City roof each winter.

The rest of the job
How it runs, what it costs and who builds it are on our main attic finishing page.
An Attic in Penn Township
Penn Township permits an attic room like any other remodel. Under the roof, two more things count: the weight the new floor must hold, and the snow that sits overhead every winter.
Penn Twp.Permits and inspections
Making attic space livable counts as an alteration in Pennsylvania, so Penn Township issues a permit and sends its own inspectors. Work is also off-limits from 9 p.m. to 7 a.m. Both rules are spelled out on the kitchen page we built for Harrison City, and we submit the paperwork.
Penn Township rules, explained30–40 psfLive load, bedrooms and other rooms
The residential code asks an uninhabited attic floor to carry 10 to 20 pounds per square foot. A bedroom needs 30, and other living space 40. That gap is why most attic joists need sistering or new joists before a subfloor and furniture go down.
Floor and joists44 in.Average yearly snowfall, Pittsburgh
Pittsburgh's airport records an average of 44.1 inches of snowfall annually, and in an attic room that weight sits directly over your ceiling. Any dormer we frame is sized to carry it, and the roofline insulation is sealed so warm air does not melt snow into ice dams.
Dormers and headroomAttic Questions
Five questions to settle before the hatch comes down for good. The attic finishing service walks through a full job.
Ask a QuestionIt depends most on three things: what the floor needs, whether a stair has to be built, and whether headroom calls for a dormer. A trussed roof that needs engineering adds to it. We price in writing after measuring the attic, and our attic service shows typical ranges.
Attic cost rangesThe residential code lets up to half of a room's required floor area sit under a ceiling lower than seven feet, but none of it under five feet, and the room needs at least 70 square feet and seven feet across. We measure those numbers at the first visit, before any design.
Dormers and headroomSometimes. Trusses are engineered as one assembly, and their diagonal webs cannot be cut or moved without a redesign approved by an engineer or the truss maker. Some trussed attics can be reworked that way. Others cannot, and then we say so and suggest another place for the room.
What we find up thereAn emergency escape window: at least 5.7 square feet of clear opening and no less than 24 inches high or 20 wide, plus a smoke alarm inside the room and a proper stair up to it. All three are drawn into the plan from day one, before framing begins.
Attic bedrooms and suitesUsually not. Most of an attic job happens above you, and Penn Township keeps construction out of the 9 p.m. to 7 a.m. window. The messiest days are when the stair opening is cut through the floor below; we seal that area off with plastic and keep every other room usable.
