Different surfaces, different methods
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: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.

Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can resealing stop a draught around my window?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Check the mastic once a year
- Keep solvents and bleach off the sealant
- Make sure the drainage slots aren’t blocked
- Wipe condensation off the frames
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Leaks usually show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
What affects the cost of window mastic
The price is agreed before any work begins. It’s based on:
- Working hours on commercial sites
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- The size of the job
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Frames and glazing around Quainton
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. With historic houses such as Waddesdon Manor (about 2.3 miles south) nearby, there’s older building stock in the area around Quainton as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Aylesbury Vale Parkway station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Church of St Mary and the Holy Cross, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Quainton Church of England School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What we do, step by step
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take most of a day for a typical house, less for a few frames. Somewhere like Quainton 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.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
How to prepare
- Clear items away from the joints we’re working on
- Mention any leaks or damp you’ve noticed
- Mention any tricky access

What we can’t put right
To be straight with you, there are a few things sealant won’t fix:
- A door that needs adjusting, rehanging or new seals
- A sash or casement that won’t close properly
- Misting between the panes of a double-glazed unit (that needs a new unit)
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
