Window Mastic in Guilton
Window mastic for Guilton and the surrounding area: careful preparation, the right product and tidy work. Call for a quick quote.
- Draughty joints inside around the window
- Rushed sealant from a window installation
- Sealant in the wrong colour for the frame
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Window mastic for homes and businesses in Guilton
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you’re dealing with leaking joints at the ends of sills and sealant in the wrong colour for the frame, we can put it right, on timber windows & doors, patio & French doors and window sills alike.
Somewhere as small as Guilton, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Different surfaces, different methods
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
What happens if it’s left?
Choosing the product is half the job. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Around Guilton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

What sealant work can’t fix
It helps to know what we cannot do:
- Damp coming through the wall itself rather than the frame joint
- A door that needs adjusting, rehanging or new seals
- Soft or decayed wood in the frame
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

What affects the cost of window mastic
The price is agreed before any work begins. It takes into account:
- The number and length of the joints
- Working hours on commercial sites
- How many areas need sealing
- Whether the work is at height
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

- What’s wrong with the joints now

Frames and glazing around Guilton
Historic houses like Goodnestone Park (about 3 miles south-west) are a reminder that the area around Guilton 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Nicholas, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Sandwich station, renewing tired window mastic between tenants heads off draught and damp complaints. Managing a site like Ash Cartwright and Kelsey Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Clean frames with a soft cloth and soapy water
- Keep paint off silicone joints
- Avoid blasting the frames with a pressure washer
- Keep solvents and bleach off the sealant
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
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.
