Temple Valley Window Mastic
Mastic around window and door frames, sills and patio doors for householders, landlords and businesses in Temple Valley. Fully insured, ARBOMaster approved and guaranteed for a year.
- Gaps between the frame and the inside reveal
- Old mastic that has gone black or come away
- Cracked sealant at the sill ends
Common problems we fix in Temple Valley
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Keep an eye out for any of the following:
- Water coming in at the bottom corners of a door
- White mastic on grey or black frames
- Rushed sealant from a window installation
- Cracked internal joints between frame and plaster
Hinton Ampner House, about 4.2 miles east, is one of the historic houses in the wider area around Temple Valley, and older homes nearby need a sealant that suits their walls.
Questions to ask before you book
- What the quote includes, VAT included or not
- Whether the sealant suits the joint
- Who does the work, and how experienced they are
- Which colour the sealant will be
About our window mastic in Temple Valley
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 have gaps where the sill meets the wall and black, perished sealant on frames, we can help, on timber windows & doors, aluminium frames and uPVC windows alike.
Homes in small places like Temple Valley often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

How the job changes by surface
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we will tell you before going ahead, as that is a job for a joiner.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Clear any debris from frame drain holes
- Don’t use solvent cleaners on the joint
- Paint up to the joint, not over it
- Keep paint and stain on wooden frames in good order
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Window mastic in Temple Valley: local notes
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. With historic houses such as Hinton Ampner House (about 4.2 miles east) nearby, there’s older building stock in the area around Temple Valley as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Winchester station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Your questions about window mastic in Temple Valley
Do you cover Temple Valley for window mastic?
Yes. We work across London and the South East, and Temple Valley is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Is Temple Valley within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Are you insured?
Yes. We’re fully insured.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
How much does window mastic cost in Temple Valley?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Leave it or put it right?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. In a small place like Temple Valley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
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.
Why choose Mr Mastic in Temple Valley
- Any old sealant cut out fully, not covered over

- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
