Is Wintershill within the area you cover?

Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can you get sealant to suit coloured frames?

How much does window mastic cost in Wintershill?

Window mastic in Wintershill, done properly
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. We work on uPVC windows, composite doors and patio & French doors, and common reasons people get in touch are draughty joints inside around the window and cracked sealant at the sill ends.
Somewhere as small as Wintershill, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

What sealant work cannot fix
To be straight with you, there are a few things sealant will not fix:
- Broken hinges, locks or handles
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Joints and surfaces we work on
- Composite doors
- uPVC windows
- Aluminium frames
- Window sills
- Timber windows & doors
- Patio & French doors
What the job involves on each surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so we pay close attention there.
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. Those corners get the most care.
How it works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on the amount of work. In a small place like Wintershill, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Do not use solvent cleaners on the joint
- Avoid blasting the frames with a pressure washer
- Keep timber frames painted
- Wipe condensation off the frames
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Leaks normally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
When to call us in Wintershill
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. Backing rod sets the right depth.
Look out for these signs:
- Untidy mastic left by window fitters
- Draughty joints inside around the window
- Mastic that’s falling out in pieces
- Cracked sealant at the sill ends
Managing a site like Wyvern Technology College? Then its window and door frames need their mastic kept sound, just like a home’s.

Wintershill homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Hedge End station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
