Frames and glazing around Broadbridge Heath
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 landlords with property near Christs Hospital station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Shelley Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Why act early in Broadbridge Heath
The work is quick compared with the damage it prevents: the visit takes a few hours for a handful of frames, longer for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Homes in smaller places like Broadbridge Heath can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Your questions about window mastic in Broadbridge Heath
Can you do window mastic in Broadbridge Heath?
Yes, Broadbridge Heath is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Christs Hospital station?

Can I paint over the new sealant?
Silicone generally won’t take paint. Let us know beforehand, and we’ll use a paintable product where it suits.
Can resealing stop a draught around my window?
In many cases. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Should I try it myself first?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What we are called out for in Broadbridge Heath
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. That’s what backing rod is for.
Most people get in touch after spotting one of these:
- Cracked or shrunken mastic around the frame
- Draughts coming in around windows and doors
- Gaps between the frame and the inside reveal
- Mastic that is falling out in pieces
In the older streets around St. John's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How the job changes by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Landlord and commercial work in Broadbridge Heath
For anyone letting property in or around Broadbridge Heath, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from an hour or two to a full day, depending on how many frames there are. In a smaller place like Broadbridge Heath, 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.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Move anything stored near the joints
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or email us.
