Pebble-Dashing & Plaster Repairs in Seaham
Seaham sits right on the North Sea, and its walls know it. PJ Plastering & Rendering Ltd apply and repair pebble-dash and Tyrolean finishes built for coastal weather, and fix the plaster and damp problems that sea air causes indoors. Based in Houghton-Le-Spring, quoting free across Seaham.
Plaster Repairs & Finishing
Finishes That Stand Up to the Coast
Salt-laden wind and driving rain off the sea are hard on exterior walls, which is exactly why pebble-dash and Tyrolean finishes have always been popular along the Durham coast. Done properly, they armour the wall: the textured surface sheds water, shrugs off knocks and hides the weathering that shows quickly on flat paint.
We apply new dash and Tyrolean, and we repair existing finishes that have cracked, hollowed or lost stones. As rendered finishes, they are covered by our 10-year rendering guarantee, and we are fully insured for domestic and commercial work.
Why It Matters
Repairing Weather-Worn Walls
A pebble-dashed wall rarely fails all at once. It goes patch by patch - a hollow area here, a shed corner there. Caught early, those patches are inexpensive to cut out and re-dash, matched to the surrounding aggregate. Left alone, water gets behind the finish, frost does its work, and a patch repair becomes a full wall.
In a former colliery town like Seaham, with plenty of solid-walled terraces facing the weather, keeping the outer skin sound is also the cheapest damp prevention there is.

Inside the House: Plaster, Damp and Artex
Indoors we patch and repair blown or cracked plaster, treat damp properly before replastering, and remove or skim over dated Artex ceilings. On coastal properties, damp is usually penetrating moisture from a weather-beaten wall or gutter rather than rising damp, and treating the right cause is the difference between a repair that lasts and one you pay for twice.
A word on Artex: coatings applied before 2000 can contain asbestos, so we recommend a quick sample test before any older ceiling is disturbed, and we will not sand or scrape a suspect coating without one.

Questions Answered
Frequently Asked Questions
Can you repair a patch of pebble-dash without redoing the whole wall?
Usually, yes. We cut the failed area back to a sound edge, rebuild the base coats and throw new dash matched as closely as possible to the existing aggregate. A fresh patch looks slightly brighter at first but weathers in. If more than about a third of the wall is hollow, re-dashing the full elevation is honestly better value.
What is Tyrolean, exactly?
Tyrolean is a cement-based finish flicked onto the wall in layers with a hand machine, building up a fine, even honeycomb texture. It is tough, breathable and very good at hiding minor imperfections, which makes it a smart choice for exposed coastal walls in Seaham.
Which is better for a house near the sea, pebble-dash or smooth render?
Both can work, but textured finishes like dash and Tyrolean are more forgiving on exposed elevations - they shed water well and small marks do not show. Smooth modern renders look sharper but show weathering sooner in harsh spots. We will recommend based on your wall's exposure, not a one-size answer.
Why do coastal homes in Seaham get more damp problems?
Wind-driven rain hits exposed walls harder and more often, and salt in the air keeps surfaces damp for longer. Any weakness - tired pointing, cracked dash, a leaking gutter - lets moisture through to the inside face, where it shows as stains or perished plaster. Fixing the outside is usually step one of fixing the inside.
Do you cover all of Seaham?
Yes. Seaham is comfortably inside our 20-mile radius from Houghton-Le-Spring, from the seafront to the newer estates, and we are along the coast road regularly.
How much does pebble-dash repair cost in Seaham?
A single patch is a modest job; full elevations cost more and depend on access and scaffolding. Every job gets a free written quote after we have seen the wall, so the price you agree to is the price you pay.
Is your dashing and Tyrolean work guaranteed?
Yes. Pebble-dash and Tyrolean are rendered finishes, so they carry our 10-year rendering guarantee. Interior repair work is backed by a fully insured firm that has its name on the van and is easy to find locally.
Can you fix damp before it ruins the plaster?
That is the ideal time to call us. If you have caught a damp patch early we can trace and treat the cause, often with minimal replastering. Once plaster has been wet for months it perishes and holds salts, and the repair becomes bigger. Early is always cheaper.
Is the Artex in my older Seaham house safe?
In good condition and left alone, generally yes. The caution is about disturbing it: textured coatings applied before 2000 can contain asbestos, so before removal or sanding we advise a simple sample test. If a test comes back positive the coating needs dealing with under the proper regulations, and we will guide you honestly on the options.
Does the weather affect when exterior work can be done?
Yes - dash, Tyrolean and render should not go on in frost or heavy rain, so winter jobs on the coast are planned around forecasts. We will always tell you straight if waiting a day or two will give your wall a better, longer-lasting finish.
