Stop Draughty Windows With Neat, Long-Lasting Frame Sealing in West Bromwich

Why the frame-to-wall seal matters

Every window frame sits in an opening in the wall, and the joint between the two is filled with sealant. Over years, that bead is asked to flex through heat, cold and vibration, shrug off sunlight and stay stuck to two materials that expand at different rates. Eventually it cracks, pulls away, or was never applied well in the first place. What you notice indoors is usually a draught across the sill, condensation pooling in the corners, black spot mould on the reveal, or a water stain that appears after driving rain.

What we check before opening a cartridge

Resealing is only the right answer if the frame, glass and wall are in decent order, so the check comes first. We look at how the frame is fixed and whether it moves when pressed, at the condition of the sills and trims, and at whether the glazing unit itself has failed — a misted double-glazed pane is a different job entirely and sealant will not touch it. We also lift the old bead in a small test area to see what is underneath, because sometimes the gap is wider or deeper than it looks and needs a backing filler before sealant will hold.

How the sealing is done

The old sealant is cut out completely — a new bead applied over old material will not bond and will peel within months. The joint is cleaned of dust, old residue and any mould, then dried. Where the gap is deep, we fill or back it appropriately so the bead is the right thickness. We then run a continuous bead of a sealant suited to the location and to the frame material — uPVC, aluminium, painted timber and masonry each need consideration — and tool it to a clean concave finish against frame and wall. Neatness matters less than coverage, but you get both.

What sealant cannot put right

Some window problems will still be there after the best reseal in the world. A rotten timber frame, a failed double-glazed unit, a cracked sill, a dropped lintel or a frame that was never fixed properly need repair or replacement by the appropriate trade. Damp that keeps coming back on the reveal despite a sound seal may be penetrating through the wall itself, particularly on older solid-brick houses common around the West Midlands. We will always tell you plainly what we can see, and reseal only where the joint genuinely is the problem — bead-over-trouble helps nobody.

Curing, cleaning and keeping it good

Fresh sealant needs time to cure before it gets wet or is painted over, so we will tell you how long to leave it per the product's instructions and how to ventilate the room meanwhile. To keep the bead in good shape, avoid bleach-heavy sprays directly on it, and wipe the sill corners dry after heavy condensation spells. A well-applied frame seal should stay flexible for years; if it starts to shrink or crack at the corners, that is the moment to have it renewed rather than wait for the draught to return.

Booking a window frame sealing visit

Tell us how many windows need attention and what you have noticed — draughts, mould, staining — when you book. Same-day visits may be available depending on the diary. On the day we will assess each window, agree with you exactly what will be done and what it will cost before starting, then carry out the work. Sealant and any backing materials are quoted separately from the labour, so you always know what you are approving.
