Window mastic for homes and businesses in Hammill Park
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on composite doors, patio & French doors and window sills, and common reasons people get in touch are old mastic that has gone black or come away and damp patches on the reveal after heavy rain.
Homes in small places like Hammill Park often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Each job carries a 12-month guarantee, whatever its size.

How we quote for window mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- The number of rooms or windows
- When we can work, for business premises
- Which sealant suits the joint
- How easy the joints are to reach
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
To help us quote quickly, please include:
- Any previous sealing or DIY work
- The rough size of the job
- The problem you’ve noticed
- The type of property

How the visit works
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a morning for a couple of windows and a door for a typical job. Somewhere as small as Hammill Park, 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work

Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why it’s worth doing now in Hammill Park
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Around Hammill Park, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Frames and glazing around Hammill Park
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. With historic houses such as Goodnestone Park (about 2.6 miles west) nearby, there’s older building stock in the area around Hammill Park as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Eastry Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Surface by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.

When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Damp problems in the wall away from the window
- A sash or casement that won’t close properly
- A frame that has rotted at the joint
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
Joints and surfaces we work on

Signs you need window mastic in Hammill Park
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
The problems people usually mention when they call include:
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
- Draughty joints inside around the window
- A bead that does not match the frame
If you let a flat or house near Sandwich station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
