What should Portsmouth homeowners expect from this work?
Portsmouth is old, coastal and dense. Downtown and the surrounding neighbourhoods hold period homes with plaster walls, deep casings and stairwells that were never built for staging, alongside a large stock of condos and rental units. Salt air runs through all of it and shortens the life of exterior coatings noticeably.
Interior work here is mostly plaster repair and careful painting. Plaster separates from lath over time, cracks run off door and window corners, and old repairs have often been patched flat onto a wall that is not flat. We refasten what is still keyed, rebuild what has let go, blend outward, and keep the period trim rather than tearing it out to save time on cutting in.
Condo and rental work downtown is a logistics job as much as a finishing job. Materials cannot be dropped wherever there is space, there is often no driveway, and shared entries and elevators have posted hours. We plan the staging with the owner or association before the first day: where the truck sits, how board comes in, where debris goes, and which hours we are actually allowed to make noise.
Exteriors on the Seacoast fail faster than inland, and pretending otherwise is how a repaint disappoints someone in four years. Salt and wind-driven rain attack the south and east elevations first, joints in trim open with freeze-thaw, and film left over old failing paint peels no matter how good the topcoat is. Prep is most of the cost here: washing, scraping back to sound material, sanding, spot-priming bare wood and re-caulking joints before any finish coat.
Because most of the housing predates 1978, lead is a real consideration whenever exterior paint gets scraped or interior surfaces get sanded. We do not test for or abate lead. Testing is the homeowner's step first, and certified contractors handle any positive result before our prep begins.
Which services does J&B do most in Portsmouth?
Portsmouth work is plaster and drywall repair in older homes, interior repaints of condo and rental units downtown, and exterior repainting on salt-exposed elevations where prep matters more than the finish coat that goes over it.

Common questions from Portsmouth homeowners
Portsmouth questions are about access, salt air and old surfaces: where the truck goes downtown, how often a coastal exterior needs repainting, whether plaster can be saved, and how association rules are handled. Answers below.
- How do you handle parking and access downtown?
- We plan it before the job, not on the morning of. That means agreeing where the truck sits, how materials come in, which entry and hours we can use, and where debris is staged. On tight streets we schedule deliveries small and often rather than one large drop.
- How often does a Portsmouth exterior need repainting?
- Coastal exposure shortens the cycle. Sheltered elevations can hold a good coating for eight years or more, while south and east faces taking salt and wind-driven rain often want attention around the five to seven year mark. Washing the salt off annually genuinely extends it.
- Can old plaster be saved, or should it be replaced?
- Most of it can be saved. Plaster still keyed to the lath is worth keeping and performs well. We refasten loose areas, rebuild only what has failed, and blend the repair into the surrounding surface so the wall reads as one plane instead of a series of patches.
- Do you work with condo associations?
- Yes. We work to posted hours, protect shared hallways and entries, remove debris rather than staging it on common property, and issue a certificate of insurance naming the association as certificate holder before we start.
