How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep jet washers away from the mastic
- Look round the frames every year or so
- Clean frames with a soft cloth and soapy water
- Wipe condensation off the frames
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Window mastic in Holbrook, done properly
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. Just phone 0345 464 0079 or drop us an email and tell us how many frames there are and how they’re reached for window mastic in Holbrook. We are often asked to deal with leaking joints at the ends of sills and sealant in the wrong colour for the frame, on composite doors, window sills and patio & French doors.
Mastic can only go onto a dry, clean joint, so window work in Holbrook is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Our work is backed for twelve months.

Surface by surface
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Honest limits
It helps to know what we can’t do too:
- Damp problems in the wall away from the window
- Rotten timber, which needs a joiner first
- A door that needs adjusting, rehanging or new seals
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

Holbrook: your questions answered
Is Holbrook within the area you cover?
Yes, Holbrook is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do window mastic in Holbrook?
Yes. Our work covers London and the South East, and Holbrook is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Can tenants book the work?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
Is the work guaranteed?
Yes. Every job comes with our 12-month guarantee, and we are ARBOMaster approved applicators.
Is the new sealant paintable?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Tell us if you’re decorating and we’ll choose accordingly.
Why act early in Holbrook
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. Older cottages and farmhouses around Holbrook can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Frames and glazing around Holbrook
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.
Schools such as Holbrook Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Warnham station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as St. Mark's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What else we do in Holbrook
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the 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.
The process
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a morning for a couple of windows and a door. Somewhere like Holbrook needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
