Window mastic in Patching, done properly
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We work on window sills, timber windows & doors and uPVC windows, and common reasons people get in touch are hard, cracked sealant around windows and a bead that doesn’t match the frame.
Outdoor sealant needs dry, clean surfaces, so work on frames around Patching is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee.

Do you need window mastic in Patching?
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
The most common problems we see are:
- Whistling draughts around closed windows
- Cracked sealant at the sill ends
- Rushed sealant from a window installation
- Sealant in the wrong colour for the frame
Rented homes near Goring-By-Sea station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before booking
- Which colour the sealant will be
- What preparation is included
- Whether they seal over old material or remove it
- What happens if they find a problem under the old sealant
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Check the mastic once a year
- Wipe condensation off the frames
- Paint up to the joint, not over it
- Avoid blasting the frames with a pressure washer
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Leaks usually show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What else we do in Patching
How we quote for window mastic
Every job gets its own quote. These are the things that affect it:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- Any working-time requirements on site
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.
What to tell us for a quote
When you call or email, these details help:
- Whether it’s a home or a business
- Whether it has been sealed before
- Roughly how big the job is
- Pictures of the joints, sent by email
Every job is quoted individually. Just phone 0345 464 0079 or send us an email with the details.
What the job involves on each surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so we pay close attention there.
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
Why it’s worth doing now in Patching
Resealing frames is a short job: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Patching, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we’ll talk you through it.

Windows and doors in Patching
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. Historic houses like Ecclesden Manor (about 1.5 miles south-west) are a reminder that the area around Patching has older buildings as well as new.

Yes. All our work carries a 12-month guarantee, and we’re fully insured.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you get sealant to suit coloured frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. We will tell you how long your job needs when we quote.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
