Window mastic for homes and businesses in Bean
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, ring 0345 464 0079 or drop us an email with the number of frames and any access details. Common call-outs are for whistling draughts around closed windows and gaps where the sill meets the wall, across timber windows & doors, patio & French doors and aluminium frames.
Homes in small places like Bean 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.
Whatever the size of the job, you get the same 12-month guarantee.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Do not paint over the silicone
- Look round the frames every year or so
- Do not aim a pressure washer at the joints
- Keep paint and stain on wooden frames in good order
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Bean questions
Can you do window mastic in Bean?
Yes. We work across London and the South East, and Bean is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Do you work for landlords with property near Greenhithe for Bluewater station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Where are you based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Can I add another job to the visit?
Yes. Just list everything you need.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Surface by surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
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.

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Damp coming through the wall itself rather than the frame joint
- Condensation trapped between the panes
- Draughts through the window seals rather than the frame
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.

What we do, step by step
The work is kept neat and contained to the area we are working on, so you can get on with your day. The job generally takes a morning for a couple of windows and a door, and we explain the cure time before we leave. Somewhere as small as Bean, 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.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
How to get a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
Related advice
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Why deal with it now?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Older cottages and farmhouses around Bean can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.

What window mastic looks like in Bean
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Bean Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Greenhithe for Bluewater station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
