Window mastic in Eastrop from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes most of a day for a typical house, less for a few frames. For a job in Eastrop, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we’re working on
- Tell us about any water getting in

How we handle window mastic in Eastrop
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We work on window sills, aluminium frames and patio & French doors, and people most often call us about gaps where the sill meets the wall and rain getting in at the frame or under the sill.
In a smaller place like Eastrop, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.
A one-year guarantee comes as standard.

Frames and glazing around Eastrop
Historic houses like The Vyne (about 2.9 miles north) are a reminder that the area around Eastrop has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in. For landlords with property near Basingstoke station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as The Costello School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What else we do in Eastrop
Why deal with it now?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Around Eastrop, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Why us?
- Experience in homes, commercial sites and hotels
- Anti-fungal sanitary silicone in wet areas
- We’re fully insured
- Any old sealant cut out fully, not covered over

What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Worn gaskets, brush seals or a door that has dropped
- Faulty window hardware
- Damp coming through the wall itself rather than the frame joint
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Eastrop: your questions answered
Can you help a landlord with a rental near Basingstoke station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Is Eastrop in your area for window mastic?
Yes. Our work covers London and the South East, and Eastrop is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Where do you work from?
Our base is Crawley. We work across South East England, London and Scotland.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear.
Does the work come with a guarantee?
Yes, for 12 months. A yearly look at the joints helps them last.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Aftercare tips
So the new joints stay in good condition:
- Walk round the house once a year and look at the joints
- Paint up to the joint, not over it
- Repaint timber before it’s bare
- Do not aim a pressure washer at the joints
Silicone cannot generally be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Leaks generally 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.
How we quote for window mastic
Jobs vary more than people expect. What affects the quote:
- Any mould that needs treating
- Which sealant suits the joint
- The number and length of the joints
- How many rooms, windows or areas are involved
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
