Window mastic in Criddlestyle
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. Common call-outs are for draughts coming in around windows and doors and white mastic on grey or black frames, on uPVC windows, patio & French doors and composite doors.
Around Criddlestyle, 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.

How much does window mastic cost in Criddlestyle?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Signs you need window mastic in Criddlestyle
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Signs it’s time to call us include:
- Draughty joints inside around the window
- Cracked sealant at the sill ends
- Rushed sealant from a window installation
- Water coming in at the bottom corners of a door
For an older house near a landmark such as St Giles, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- What insurance they hold
- Which sealant they’ll use, and why
- Who does the work, and how experienced they are
What the job involves on each surface
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
What else we do in Criddlestyle
DIY versus a professional finish
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How to look after the new joints
So the new joints stay in good condition:
- Keep timber frames painted
- Keep jet washers away from the mastic
- Clear any debris from frame drain holes
- Air rooms to keep condensation down around windows
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
How it works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It generally takes most of a day for a typical house, less for a few frames. Somewhere as small as Criddlestyle, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints

Windows and doors in Criddlestyle
With historic houses such as Breamore House (about 3 miles north) nearby, there’s older building stock in the area around Criddlestyle as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as The Burgate School and Sixth Form, the mastic around its windows and doors needs looking after like any other building’s.
