About our window mastic in Bearsted
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. If the draught is through the window seals instead, we will tell you. If you have white mastic on grey or black frames and old mastic that has gone black or come away, we can help, on composite doors, patio & French doors and aluminium frames alike.
In a smaller place like Bearsted, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
All our work is covered by our 12-month guarantee.

What else we do in Bearsted
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Signs you need window mastic in Bearsted
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Any of these means the joints need attention:
- Sealant in the wrong colour for the frame
- Gaps where the sill meets the wall
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
Managing a site like Thurnham Church of England Infant School? Then the mastic around its windows and doors needs looking after like any other building’s.

Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we will choose accordingly.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Are you fully insured?
Yes, we are fully insured.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Do not use solvent cleaners on the joint
- Wipe condensation off the frames
- Wash the frames with mild soapy water
- Avoid blasting the frames with a pressure washer
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
What window mastic looks like in Bearsted
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Stoneacre (about 1.3 miles south) nearby, there’s older building stock in the area around Bearsted as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
In the older streets around Holy Cross Church, the joint between an old wall and a newer frame is normally the first place rain gets in. Rented homes near Bearsted station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

The process
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of frames, longer for a whole house. A visit to Bearsted is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we look at every frame and agree the list.
- 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.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Before we arrive
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before

How the job changes by surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that.
