Shed and Outbuilding Painting Services
Garden Sheds
A garden shed that has not been treated for several years will have open grain, surface cracking in the boards, and biological growth on shaded or north-facing faces. Applying shed paint directly to timber in this condition gives poor adhesion — a finish that lifts and peels within one to two seasons results.
Correct preparation involves cleaning the surface with mould treatment to remove moss, algae, and lichen, then allowing the timber to dry thoroughly before applying a penetrating wood preservative. We assess every shed before quoting — if boards are rotten or the structural condition is poor, we advise on that before starting work.
Timber Workshops and Outbuildings
Larger timber buildings have more surface area and typically more weathering variation between faces. South-facing faces dry faster and may need less preparation. North-facing faces that stay damp under shade have heavy biological growth and more open grain.
We treat each face of the building according to its condition. For properties where outbuilding painting is combined with exterior painting on the main house, we schedule both as a single project to minimise disruption.
Summerhouses and Garden Rooms
Summerhouses and garden rooms are often more visible features than a standard shed — the finish quality matters more and the choice of colour is usually part of the brief. We treat summerhouses with the same care as any visible exterior surface, paying more attention to visible joint lines and decorative features.
Modern garden rooms sometimes clad in composite materials require a different preparation system. We advise at the site visit on the correct approach for composite cladding.
Timber Preservative Treatments
A penetrating wood preservative is the correct first treatment on aged or bare timber. It protects the wood from the inside by penetrating the grain rather than sitting on the surface. Standard shed paint without a preservative base coat will not achieve the same service life.
On older timber with open grain and surface cracking, a penetrating oil or preservative is applied first to draw deep into the wood and stabilise the surface before a topcoat is applied. This two-stage approach is recommended for any timber shed or outbuilding that has not been treated in the last three to four years.

Our Shed Painting Process
1. Assessment
We examine the shed or outbuilding condition, identify rotten sections, assess biological growth levels, and confirm the scope of work. We advise on any boards or sections that need replacing before treatment.
2. Cleaning
Biological growth is treated with a mould treatment and rinsed off. Loose and peeling old coating is removed by wire brushing or scraping. The surface must be clean and dry before any product is applied.
3. Preservative Application
A penetrating wood preservative is applied on aged or bare timber. This is absorbed into the grain and forms the base layer for the topcoat.
4. Topcoat Application
One or two coats of the agreed shed stain or paint are applied by brush. We work the product into joints, overlaps, and edges to ensure full coverage. The top of each board and any overhangs are treated as priority areas.
5. Final Inspection
We check all faces for missed areas and thin coverage. Touch-ups are done before leaving. We advise on a realistic retreatment interval based on the exposure and condition of the timber.
Shed Painting Costs in Haywards Heath
Prices below are estimates only. Every structure is different. Call 01444 719922 for a precise quote.

What Drives the Price
Shed painting typically costs between £200 and £700 for a standard garden shed, depending on size, condition, and the treatment system used. A standard 6×4 shed costs less than a large workshop — combined shed and outbuilding blocks cost more.
Timber condition is the other key factor. Heavily weathered timber with significant biological growth requires more preparation than a newer, better-maintained structure.
Typical Price Ranges
Standard garden shed in Burgess Hill or Scaynes Hill — approx. 10 sq metres, moderate weathering, clean and two coats: £250–400.
Larger shed or timber workshop in Haywards Heath central or Hurstpierpoint — approx. 18 sq metres, mould treatment, preservative, and topcoat: £400–650.
Rural and Older Properties
Timber outbuilding at an Ardingly or Cuckfield rural property — approx. 25 sq metres, older timber, full preparation and two-stage treatment: £550–900.
Rural properties in Ardingly commonly have older timber outbuildings shaded by established trees. Shaded timber holds moisture, develops more biological growth, and typically needs a longer drying period before treatment begins.
