Plastering is applying a smooth finishing coat of plaster to walls and ceilings, either as a thin skim over sound surfaces or as a full re-plaster after removing failed plaster, creating a flat surface ready for decoration.
We take on plastering and skimming throughout Caernarfon and the surrounding LL55 postcodes, as well as in Bangor, Gwynedd, Holyhead and Llandudno. The guide range for this work in Wales is £500–£1,450 including VAT; where your project falls depends on its size, the materials you pick and how easy the site is to reach. A free survey turns that range into a fixed figure.

Local housing and plastering and skimming
Slate defines much of Gwynedd, from quarrying villages such as Bethesda and Blaenau Ffestiniog with their stone terraces to slate roofs across the county. Bangor and Caernarfon have Victorian and Georgian streets, Anglesey has stone cottages and bungalows, and resorts such as Pwllheli and Barmouth have Victorian terraces and newer bungalows.
Stone and slate homes need breathable lime render and pointing, and slate roofs often need careful repair rather than replacement. Terraces suit loft conversions, and bungalows commonly take extensions and window upgrades.
So when we survey a Caernarfon property for plastering and skimming, the first step is working out how it was built and what has been changed since.
Planning and building rules in Caernarfon
Because Caernarfon falls under Wales's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
Internal improvements do not need planning permission in Wales unless the building is listed.
Building Regulations in Wales cover notifiable electrical work, drainage, ventilation and any structural change.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
We look at the job
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for plastering and skimming so the price reflects your home.
Price and scope agreed
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Booking the work
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Caernarfon property.
The work itself
Our trades complete plastering and skimming while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.
What you can expect from us
Frequently asked questions
How much will plastering and skimming cost in Caernarfon?
As a guide, expect to pay £500–£1,450 including VAT for plastering and skimming in Caernarfon. That range is adjusted for Wales, which runs about 8% below the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
Should older houses be plastered with lime?
Older homes with solid walls and no damp-proof course are often better with lime plaster, because it lets moisture move through the wall and evaporate. Modern gypsum plaster can trap moisture in these walls, which can cause damp patches and blown plaster. Lime takes longer to apply and dry, so it costs more. We check your wall construction before recommending a material.
What is the difference between skimming and re-plastering?
Skimming applies a thin finishing coat, a few millimetres thick, over plaster or plasterboard that is still sound. Re-plastering removes the old plaster back to the brick or block and applies new base and finishing coats. Skimming is quicker and cheaper, but if the existing plaster is loose, hollow or crumbling, a skim will not hold. We tap-test walls to decide which is needed.
How messy is plastering?
Plastering is wet work, so some mess is unavoidable, but good protection keeps it under control. We cover floors with dust sheets, mask sockets, switches and skirting, and move or cover furniture. Removing old plaster creates the most dust, so we seal doorways and keep the area ventilated. At the end, we clear waste and leave the room tidy and ready for decorating.
How long will plastering and skimming take?
On a typical home, allow 1–3 days per room, plus drying time. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
