How it works
Before we leave, we go over the finished joints with you. The work normally takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. In a small place like Boughton Green, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
- Mention any tricky access

How we handle window mastic in Boughton Green
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you have damp patches on the reveal after heavy rain and gaps between the frame and the inside reveal, we can put it right, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Boughton Green is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
A one-year guarantee comes as standard.

What the job involves on each surface
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
What else we do in Boughton Green
Aftercare tips
To keep the joints looking good and working properly:
- Make sure the drainage slots are not blocked
- Do not aim a pressure washer at the joints
- Keep paint and stain on wooden frames in good order
- Wash the frames with mild soapy water
Most silicone sealants won’t take paint, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Quotes for window mastic in Boughton Green
We do not publish a price list. The quote depends on:
- When we can work, for business premises
- The amount of work
- Any mould that needs treating
- Which sealant suits the joint
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.
What we need to know
When you contact us, these details help:
- The type of property
- How we’d reach the joints
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
For a quote, ring 0345 464 0079 or email us with the location and a short description of the problem. You will have a clear quote before we start.
Work for landlords, hotels and businesses
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Boughton Green: your questions answered
Can you do window mastic in Boughton Green?
Yes, Boughton Green is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Do you cover smaller places like Boughton Green?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How long will my window job take?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
Window mastic in Boughton Green: local notes
With historic houses such as Stoneacre (about 2.5 miles north-east) nearby, there’s older building stock in the area around Boughton 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Coxheath Congregational Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Boughton Monchelsea Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to East Farleigh station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
