Window & door mastic in Compton, Hampshire
Mastic around window and door frames, sills and patio doors for householders, landlords and businesses in Compton. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Water coming in at the bottom corners of a door
- Old mastic that has gone black or come away
- Gaps left after new windows were fitted
What we are called out for in Compton
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 cannot flex. That’s what backing rod is for.
Signs it’s time to call us include:
- Gaps left after new windows were fitted
- Gaps where the sill meets the wall
- Rain getting in at the frame or under the sill
- White mastic on grey or black frames
If you live in an older home near Church of All Saints, the joint between an old wall and a newer frame is generally the first place rain gets in.
What to look for in a quote
- When the joint can take water or movement
- Who does the work, and how experienced they are
- The length of the guarantee
- How the surfaces are prepared before sealing
Window mastic in Compton, done properly
From a single sill to a whole house of windows, you’ll get a clear quote before we start. Just ring 0345 464 0079 or email us and tell us how many frames there are and how they’re reached for window mastic in Compton. Typical jobs include gaps between the frame and the inside reveal and gaps where the sill meets the wall, on timber windows & doors, window sills and patio & French doors.
Homes in small places like Compton often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Compton questions
Do you cover Compton for window mastic?
Yes, Compton is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.
Do you cover smaller places like Compton?
Yes, Compton is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels.
Can new window sealant be painted?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we will choose accordingly.
How long does it take to reseal the windows on a house?
The work takes a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
Landlord and commercial work in Compton
Landlords and agents in Compton can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Draughts through the window seals rather than the frame
- Damp problems in the wall away from the window
- A sash or casement that will not close properly
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
What we seal
- Patio & French doors
- Window sills
- uPVC windows
- Aluminium frames
- Timber windows & doors
- Composite doors
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
What else we do in Compton
The process
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours for a few frames, or a day or more for a whole house, depending on how much there is to do. Somewhere as small as Compton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, 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.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
How to get a quote

Related advice
Why it’s worth doing now in Compton
Once mastic fails, rain can get between the frame and 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 Compton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- White, clear, grey or another colour, product permitting
- Old sealant always removed completely
- We agree the colour with you first

The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Compton All Saints Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
