How we handle window mastic in Woollensbrook
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so deep gaps get backing rod first. The sealant then grips the two sides it should. Typical jobs include mastic that’s falling out in pieces and water coming in at the bottom corners of a door, on composite doors, patio & French doors and aluminium frames.
Around Woollensbrook, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Big or small, it’s backed by our 12-month guarantee.

Windows and doors in Woollensbrook
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.
In the older streets around Church of St Catherine & St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Rye House station, renewing tired window mastic between tenants heads off draught and damp complaints.

How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. Somewhere like Woollensbrook needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.

Common questions in Woollensbrook
Is Woollensbrook in your area for window mastic?
Yes, Woollensbrook is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Do you cover smaller places like Woollensbrook?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
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.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Mention any painting plans before we start.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
Leave it or put it right?
Resealing frames is a short job: it takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Older cottages and farmhouses around Woollensbrook can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Different surfaces, different methods
Composite doors
Front doors take the weather head on. We pay most attention there.
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 keeps the clean look.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint
- Broken hinges, locks or handles
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before you book.
What we seal
- Composite doors
- Patio & French doors
- Timber windows & doors
- Aluminium frames

What we are called out for in Woollensbrook
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Keep an eye out for any of the following:
- Water coming in at the bottom corners of a door
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
- Gaps left after new windows were fitted
Managing a site like Westfield Community Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

- When the joint can take water or movement
