Window mastic in Peper Harow
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. Common call-outs are for leaking joints at the ends of sills and draughty joints inside around the window, across timber windows & doors, window sills and patio & French doors.
Around Peper Harow, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

What we do, step by step
On the day, we start by going over the job with you. Surfaces next to the work are protected before we start. The work usually takes most of a day for a typical house, less for a few frames. In a small place like Peper Harow, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints

Advice
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
How to look after the new joints
So the new joints stay in good condition:
- Repaint timber before it’s bare
- Wash the frames with mild soapy water
- Keep drainage slots and sill grooves clear
- Check the mastic once a year
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.

How the job changes by surface
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Common questions in Peper Harow
Can you help a landlord with a rental near Godalming station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Will you come out to Peper Harow?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can resealing stop a draught around my window?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Where are you based?
We work from Crawley. We cover Peper Harow and the rest of Surrey.
Do you need window mastic in Peper Harow?
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
These are the problems we’re asked about most:
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
- White mastic on grey or black frames
- Gaps between the frame and the inside reveal
Schools such as St Mary's CofE Voluntary Controlled Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Why act early in Peper Harow
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Older cottages and farmhouses around Peper Harow can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

What window mastic looks like in Peper Harow
Historic houses like Wanborough Manor (about 3 miles north) are a reminder that the area around Peper Harow has older buildings as well as new. 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Nicholas, the joint between an old wall and a newer frame is generally the first place rain gets in. Letting a property close to Godalming station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
