Window & door mastic in Eastleigh, Hampshire
Window and door frames in Eastleigh need attention? We remove the old material, prepare the joints and seal them properly.

About our window mastic in Eastleigh
Around Eastleigh we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Typical jobs include cracked sealant at the sill ends and rain getting in at the frame or under the sill, on uPVC windows, timber windows & doors and composite doors.
Eastleigh mixes older streets, where windows have often been replaced, with newer estates fitted with uPVC. In every case, the joint between frame and wall is what keeps water out.
You get a 12-month guarantee, the same in Eastleigh as everywhere else we work.
Windows and doors in Eastleigh
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. Historic houses like South Stoneham House (about 2.5 miles south-west) are a reminder that the area around Eastleigh has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Eastleigh station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Norwood Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

How the visit works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for a few frames, or a day or more for a whole house in most cases. In Eastleigh, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Avoid blasting the frames with a pressure washer
- Air rooms to keep condensation down around windows
- Keep paint and stain on wooden frames in good order
- Check the mastic once a year
Try not to touch the new joint while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Surface by surface
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.

FAQs for Eastleigh
Is Eastleigh in your area for window mastic?
Yes. We work across London and the South East, and Eastleigh is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
I let a flat near Eastleigh station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How do I get a quote for window mastic in Eastleigh?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.
What do you need from me for a quote?
Tell us what needs doing and where. If we need more, we’ll ask.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can you seal the gap between the frame and the plaster indoors?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and they’re far easier to fix early.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Signs you need window mastic in Eastleigh
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. Backing rod sets the right depth.
Keep an eye out for these signs:
- Gaps left after new windows were fitted
- Mastic that is falling out in pieces
- A bead that doesn’t match the frame
- Cracked or shrunken mastic around the frame
In the older streets around Church of the Resurrection, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include

- Who turns up on the day
- How the colour is chosen
- Whether they’re fully insured
