Window Frame Painters in Winchester

Timber sash windows on Winchester’s Georgian and Victorian properties are one of the most technically demanding external painting jobs. The window has multiple moving parts, softwood that swells in winter and shrinks in summer, and often carries decades of paint build-up.

Georgian properties in the Cathedral Quarter on The Square and Broad Street in Alresford retain original double-hung sash windows. Many of these sashes are stiff or painted shut from previous decoration carried out without correct preparation.

A sash that is painted shut is not just a convenience problem. The sash box is also sealed.

This prevents moisture from escaping and causes decay in the sash rail and pulley stile.

We free painted-shut sashes by cutting the paint seal at the meeting rail and along the staff beads before starting any preparation. This restores operation before we strip or sand the frame.

We remove old paint build-up from the sash and frame. We fill any cracks along the grain, prime bare timber, and apply two finish coats with the sashes in their correct positions.

The result is a window that opens freely and is sealed against weather rather than sealed shut. Our sash window work links with our exterior painting service for clients who need the full house front done at the same time.

Casement windows are generally more straightforward than sash windows because they have fewer moving parts. The main preparation task is dealing with paint build-up on the frame and around the opening edge of the casement itself.

Paint build-up on the meeting face of a casement is the most common reason casement windows stick. Casements also lose their weather seal when the paint seal on the rebate face cracks and opens.

We sand back the meeting faces, prime any bare areas, and apply the finish coat with the casement in the open position to ensure full coverage on the rebate.

On Weeke and Stanmore properties with 1950s and 1970s casement windows, the frames are often in better condition than period sash windows. Some may have had unsuitable products applied in the past.

We assess the existing paint system at the quotation visit and advise on whether a full strip or a preparation-and-repaint is the right approach.

uPVC window frames can be repainted in a specialist exterior finish that adheres to the uPVC surface without peeling. This is a cost-effective alternative to frame replacement and produces a result that is almost indistinguishable from new.

The preparation process for uPVC repainting is critical. We degrease the frame, abrade the surface to create a key, and apply a specialist adhesion primer before the colour coat.

Without the adhesion primer, most paints will lift from uPVC within one season. With correct preparation, the finish will hold for five to eight years.

uPVC repainting is particularly common on Badger Farm and Stanmore estate properties where the original white frames have yellowed or been updated to a cream or anthracite colour. We can repaint the frames to any RAL or BS colour on request.

Fascias, soffits, and window sills are closely related to window frame painting and are most cost-effectively included in the same visit. The preparation needs are similar and the scaffolding or access equipment needed for upper-floor frames covers these elements at the same time.

Timber fascias and soffits in Winchester need regular attention. They are in a vulnerable position at the eaves and are the first element to show the effects of moisture and UV exposure on most houses.

We sand back any flaking paint, fill any open joints at the fascia-soffit intersection, prime bare areas, and finish in the agreed colour.

Window sills are the most rain-exposed joinery element on the outside of a house. They shed water directly onto the wall below.

A sill that is not properly sealed at the front edge and at the joints with the frame will channel water into the wall rather than away from it. We prime sill ends and undersides as part of standard preparation.

See our front door painting and door painting pages for related external joinery services.

The quality of a window frame repaint is almost entirely determined by the quality of the preparation. A finish coat applied to a properly prepared frame will look better and last significantly longer than the same coat applied over old flaking paint on a frame that has been wiped down and painted over.

On timber frames with multiple old paint layers, we use a combination of heat gun and hand scraper, chemical stripper on moulded profiles, and orbital sander on flat sections. The goal is a clean, stable surface rather than necessarily getting back to bare timber on every section.

Where the old paint is sound and well-adhered, we sand and prime over it. Where it is flaking or soft, we take it back.

Priming bare timber uses an oil-based or masonry primer that seals the wood and gives the finish coat a stable, non-absorbent foundation. On sills and sash rails, which have direct water exposure, we apply a two-coat primer system.

This is the part of the job that prevents water from getting into the end grain and starting the rot cycle. That rot cycle is the main threat to original period window frames.
