Window mastic in Upper Horsebridge
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. If you have white mastic on grey or black frames and rain getting in at the frame or under the sill, we can help, on window sills, composite doors and uPVC windows alike.
In smaller places like Upper Horsebridge, 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.
Big or small, you get the same 12-month guarantee.

Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. Homes in smaller places like Upper Horsebridge can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Upper Horsebridge homes and the weather
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. With historic houses such as Horselunges Manor (about 0.6 miles north-west) nearby, there’s older building stock in the area around Upper Horsebridge as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Hawkes Farm Academy, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Polegate station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Horselunges Manor, about 0.6 miles north-west, is one of the historic houses in the wider area around Upper Horsebridge, and older homes nearby need a sealant that suits their walls.

For landlords and businesses
We work for letting agents and landlords as well as homeowners. Resealing between tenancies keeps a property looking cared for.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Looking after it afterwards
Looking after new joints is easy:
- Clear any debris from frame drain holes
- Use gentle cleaners on frames and sealant
- Keep timber frames painted
- Paint up to the joint, not over it
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
What happens on the day
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a few frames, or a day or more for a whole house. In a smaller place like Upper Horsebridge, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Before we arrive
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
Getting a quote
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand.
Advice
Upper Horsebridge: your questions answered
Do you work for landlords with property near Polegate station?
Yes. We work for landlords and agents as well as householders. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you cover Upper Horsebridge for window mastic?
Yes. Our work covers London and the South East, and Upper Horsebridge is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
How do I get a quote for window mastic in Upper Horsebridge?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Can you match the sealant to my frames?
Normally, yes. Mention the frame colour when you ask for a quote and we’ll use the nearest match.
Can you reach windows above the ground floor?
Usually, yes. We plan safe access before the job, so mention the height and anything in the way.
How long does it take to reseal the windows on a house?
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.
Different surfaces, different methods
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.
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.
When something else is needed
To be straight with you, some problems need a different trade:
- Penetrating damp from a failed cavity tray or render
- A frame that has rotted at the joint
- Faulty window hardware
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.
