Window & door mastic in Walton on the Hill, Surrey
Window and door frames in Walton on the Hill need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Water coming in at the bottom corners of a door
- Black, perished sealant on frames
- Cracked or shrunken mastic around the frame
Different surfaces, different methods
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
About our window mastic in Walton on the Hill
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We’re often asked to deal with draughty joints inside around the window and leaking joints at the ends of sills, on patio & French doors, timber windows & doors and aluminium frames.
Homes in small places like Walton on the Hill 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 will put it right.

Windows and doors in Walton on the Hill
With historic houses such as Fitznells Manor (about 5 miles north) nearby, there’s older building stock in the area around Walton on the Hill as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
Letting a property close to Tadworth station? Then 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 Peter, the joint between an old wall and a newer frame is usually the first place rain gets in. Managing a site like Walton-on-the-Hill Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

The process
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take most of a day for a typical house, less for a few frames. Somewhere as small as Walton on the Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- 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.

Walton on the Hill questions
Will you come out to Walton on the Hill?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Tadworth station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Can you do upstairs windows?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we will confirm what’s needed.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you when we finish.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Other services in Walton on the Hill
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Walk round the house once a year and look at the joints
- Wash the frames with mild soapy water
- Clear any debris from frame drain holes
- Keep solvents and bleach off the sealant
Silicone cannot normally be painted, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
