Stoneyhills Window Mastic
We cover Stoneyhills for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Mastic that’s falling out in pieces
- Gaps between the frame and the inside reveal
- Hard, cracked sealant around windows
Surface by surface
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
How we handle window mastic in Stoneyhills
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. If you are dealing with cracked sealant at the sill ends and gaps left after new windows were fitted, we can help.
Homes in small places like Stoneyhills 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 stand behind the work with a one-year guarantee, so you’re covered after we have gone.

When to call us in Stoneyhills
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
Common reasons people contact us include:
- Draughts coming in around windows and doors
- A bead that doesn’t match the frame
- Damp patches on the reveal after heavy rain
- Untidy mastic left by window fitters
If you live in an older home near St Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- Are they insured?
- Which sealant they’ll use, and why
- Who turns up on the day
- The length of the guarantee

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Leave it or put it right?
Failed mastic isn’t a reason to replace sound 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. Around Stoneyhills, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What you get with us
- Homes, businesses and hotels
- A 12-month guarantee on all work

How much does window mastic cost in Stoneyhills?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. You’ll know the timing when we quote.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Do you have insurance?
Yes. We’re fully insured.
When it is not the sealant
To be straight with you, there are a few things sealant won’t fix:
- Broken hinges, locks or handles
- Draughts through the window seals rather than the frame
- Penetrating damp from a failed cavity tray or render
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

How it works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of frames, longer for a whole house. Somewhere like Stoneyhills needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on
- Plan for the work area to be out of bounds to pets and children
