Window mastic in Allington
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. Typical jobs include gaps between the frame and the inside reveal and cracked or shrunken mastic around the frame, across uPVC windows, patio & French doors and timber windows & doors.
In smaller places like Allington, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
We stand behind the work with a 12-month guarantee.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a few frames, or a day or more for a whole house and we leave things clean and tidy. A visit to Allington is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- 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.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can

FAQs for Allington
I let a flat near Barming station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you cover smaller places like Allington?
Yes. Allington is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Is the work guaranteed?
Yes, with our 12-month guarantee. A yearly look at the joints helps them last.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can new window sealant be painted?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Tell us if you are decorating and we’ll choose accordingly.
Can you reach windows above the ground floor?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
What the job involves on each surface
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
For landlords and businesses
For anyone letting property in or around Allington, several properties can go on one quote. Send us the addresses and the work at each, and photos by email help.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Frames and glazing around Allington
Historic houses like Stoneacre (about 4.2 miles south-east) are a reminder that the area around Allington 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.
Managing a site like Allington Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as St. Nicholas' Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wipe condensation off the frames
- Keep jet washers away from the mastic
- Check the mastic once a year
- Wash the frames with mild soapy water
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.

Common problems we fix in Allington

The problems people generally mention when they call include:
- Gaps where the sill meets the wall
- Draughty joints inside around the window
- Sealant in the wrong colour for the frame
- Whistling draughts around closed windows
