Window Mastic in Kemptown
Problem with your window and door frames in Kemptown? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Cracked sealant at the sill ends
- Damp patches on the reveal after heavy rain
- Old mastic that has gone black or come away
How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes anything from an hour or two to a full day, depending on how many frames there are. A visit to Kemptown 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.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

Advice
About our window mastic in Kemptown
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We work on composite doors, window sills and patio & French doors, and common reasons people get in touch are hard, cracked sealant around windows and old mastic that has gone black or come away.
Around Kemptown, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
You get a one-year guarantee, the same in Kemptown as everywhere else we work.

Kemptown: your questions answered
Can you help a landlord with a rental near Brighton station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover smaller places like Kemptown?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
What should I tell you?
Let us know what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.
Is the work guaranteed?
Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Is the new sealant paintable?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Tell us if you are decorating and we’ll choose accordingly.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.

Leave it or put it right?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Homes in smaller places like Kemptown 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.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What you get with us
- Domestic, commercial and hotel work
- Any old sealant cut out fully, not covered over
- ARBOMaster approved applicator
- One-year guarantee on every job

Common problems we fix in Kemptown
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
These are the problems we’re asked about most:
- Rain getting in at the frame or under the sill
- Draughty joints inside around the window
- Gaps where the sill meets the wall
- Draughts coming in around windows and doors
Homes close to St George's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before booking
- When the joint can take water or movement
- How the joint is cleaned and prepared
- Whether they seal over old material or remove it
- Who turns up on the day
What window mastic looks like in Kemptown
Kemptown is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Brighton station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How the job changes by surface
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that.
