Window mastic for homes and businesses in Turville Heath
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we will tell you. We work on patio & French doors, composite doors and window sills, and people most often call us about draughts coming in around windows and doors and sealant in the wrong colour for the frame.
Homes in small places like Turville Heath 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.
Every job comes with our 12-month guarantee.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Keep paint off silicone joints
- Clean frames with a soft cloth and soapy water
- Avoid blasting the frames with a pressure washer
- Walk round the house once a year and look at the joints
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
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.
What happens on the day
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a morning for a couple of windows and a door for a typical job. In a small place like Turville Heath, access is usually the main thing to plan. 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.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive

- Black, perished sealant on frames
- Gaps between the frame and the inside reveal
- Damp patches on the reveal after heavy rain
- Draughts coming in around windows and doors
Stonor Park, about 1 mile south, is one of the historic houses in the wider area around Turville Heath.

How the job changes by surface
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as a joiner will need to deal with it.
Common questions in Turville Heath
Is there a guarantee on window mastic in Turville Heath?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Turville Heath?
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.
How long before the joint can be used?
Cure times vary by product. Before we leave, we will tell you the cure time.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
How many windows can you do in a day?
Allow anything from an hour or two to a full day, depending on how many frames there are. Access and how stubborn the old mastic is affect the time most.
Windows and doors in Turville Heath
With historic houses such as Stonor Park (about 1 mile south) nearby, there’s older building stock in the area around Turville Heath as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What affects the cost of window mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Whether there’s mould to deal with
- The old material and how stubborn it is
- How many areas need sealing
- Whether the work is at height
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The rough size of the job
- Where the property is
- Any access issues, like height or stairs
- If someone has resealed it before
