Window Mastic in Gill's Green
Mastic around window and door frames, sills and patio doors for householders, landlords and businesses in Gill's Green. Fully insured, ARBOMaster approved and guaranteed for a year.
- Cold air getting in at the frame edge
- Rain getting in at the frame or under the sill
- Gaps between the frame and the inside reveal
How we handle window mastic in Gill's Green
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; 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 have mastic that’s falling out in pieces and sealant in the wrong colour for the frame, we can put it right, on window sills, timber windows & doors and composite doors alike.
Around Gill's Green, 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.
All our work is covered by our one-year guarantee, wherever you are in Kent.

Leave it or put it right?
Choosing the product is half the job. Interior caulk and bathroom silicone aren’t made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. In a small place like Gill's Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

The process
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Gill's Green, access is normally the main thing to plan. 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.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed

Advice
Signs you need window mastic in Gill's Green
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. That’s what backing rod is for.
The most common problems we see are:
- Cracked internal joints between frame and plaster
- Mastic that is falling out in pieces
- Cracked or shrunken mastic around the frame
- Sealant in the wrong colour for the frame
Letting a property close to Etchingham station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

DIY sealant or a professional job?
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.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Looking after it afterwards
After the cure time, these simple habits help:
- Keep timber frames painted
- Keep solvents and bleach off the sealant
- Use gentle cleaners on frames and sealant
- Paint up to the joint, not over it
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.

Frames and glazing around Gill's Green
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. With historic houses such as Scotney Castle (about 4.8 miles north-west) nearby, there’s older building stock in the area around Gill's Green as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For site and facilities teams at buildings such as Marlborough House School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of All Saints, the joint between an old wall and a newer frame is generally the first place rain gets in.
