When to call us in Wyck
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
The problems people generally mention when they call are:
- Water coming in at the bottom corners of a door
- Gaps left after new windows were fitted
- Sealant in the wrong colour for the frame
- Draughty joints inside around the window
Rented homes near Alton station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How we handle window mastic in Wyck
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you’re dealing with whistling draughts around closed windows and cracked internal joints between frame and plaster, we can put it right, on timber windows & doors, window sills and composite doors alike.
Somewhere as small as Wyck, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee, large or small.

How the job changes by surface
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- A frame that has rotted at the joint
- Broken hinges, locks or handles
- A failed sealed unit that has misted up
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Wash the frames with mild soapy water
- Don’t aim a pressure washer at the joints
- Repaint timber before it’s bare
- Air rooms to keep condensation down around windows
Most silicone sealants will not take paint, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.

Can new window sealant be painted?

Can you seal over the old sealant?

Why act early in Wyck
A quick bead over the top of old mastic looks like an easy fix, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. In a small place like Wyck, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
