Window mastic in Rowhook
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and we give a 12-month guarantee on the work. Typical jobs include damp patches on the reveal after heavy rain and gaps where the sill meets the wall, on composite doors, timber windows & doors and window sills.
Around Rowhook, 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.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

What else we do in Rowhook
What window mastic looks like in Rowhook
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Warnham station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you look after a building such as Farlington School, its window and door frames need their mastic kept sound, just like a home’s.

When something else is needed
Before booking, it’s worth knowing the limits:
- Damp problems in the wall away from the window

Surfaces we seal
- Window sills

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Check the mastic once a year
- Keep paint and stain on wooden frames in good order
- Keep solvents and bleach off the sealant
- Make sure the drainage slots are not blocked
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
What happens on the day
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes most of a day for a typical house, less for a few frames. In a small place like Rowhook, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Before we arrive
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

How the job changes by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Why act early in Rowhook
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. Proper resealing starts with removing the old joint. Where a wall is exposed, as many are in small places like Rowhook, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.
