How we handle window mastic in Rooksdown
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you are dealing with draughty joints inside around the window and rain getting in at the frame or under the sill, we can put it right, whatever the surface.
Many houses in smaller places like Rooksdown have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Window mastic in Rooksdown: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as The Vyne (about 2.2 miles north-east) nearby, there’s older building stock in the area around Rooksdown as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
The Vyne, about 2.2 miles north-east, is one of the historic houses in the wider area around Rooksdown. For site and facilities teams at buildings such as Fort Hill Community School, the mastic around its windows and doors needs looking after like any other building’s.

Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Damp coming through the wall itself rather than the frame joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A door that needs adjusting, rehanging or new seals
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.
Joints and surfaces we work on
- uPVC windows
- Window sills
- Composite doors
- Aluminium frames
- Patio & French doors
- Timber windows & doors
Leave it or put it right?
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. Around Rooksdown, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Why Rooksdown clients choose us
- Quality sealants from Arbo and Everbuild
- Experience in homes, commercial sites and hotels
- White, clear, grey or coloured to suit, where the product allows
- Sanitary silicone with an anti-fungal additive in wet areas
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What the job involves on each surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it without cracking.
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall.

Where is Mr Mastic based?
We work from Crawley. Our applicators cover Rooksdown.
Will new mastic stop draughts?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.
Signs you need window mastic in Rooksdown
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, so it comes away long before its time.
Any of these means the joints need attention:
- White mastic on grey or black frames
- Cracked internal joints between frame and plaster
- Rain getting in at the frame or under the sill
- Mastic that’s falling out in pieces
Letting a property close to Basingstoke station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a few frames, or a day or more for a whole house and we leave things clean and tidy. A visit to Rooksdown 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.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Tell us if parking is tricky
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
