Window mastic in Halland, done properly
Around Halland we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on patio & French doors, timber windows & doors and window sills, and the jobs we see most are rushed sealant from a window installation and mastic that has split away from the wall.
Somewhere as small as Halland, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All of our work is guaranteed for twelve months.

Surface by surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.

Frames and glazing around Halland
Historic houses like Glyndebourne (about 4.8 miles south-west) are a reminder that the area around Halland has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Uckfield station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Glyndebourne, about 4.8 miles south-west, is one of the historic houses in the wider area around Halland.

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. It generally takes a morning for a couple of windows and a door. Somewhere as small as Halland, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- On commercial sites, let us know about site rules
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed

Advice
What happens if it’s left?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. In a small place like Halland, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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.
Why us?
- Tidy, careful work
- A choice of colours where the product allows
- Domestic, commercial and hotel work
- We’re fully insured

What we can’t put right
To be straight with you, some problems need a different trade:
- A door that needs adjusting, rehanging or new seals
- 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)
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal
- uPVC windows
- Patio & French doors
- Window sills
- Aluminium frames
- Timber windows & doors
- Composite doors
When to call us in Halland
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
Keep an eye out for these signs:
- Water coming in at the bottom corners of a door
- Cracked internal joints between frame and plaster
- Untidy mastic left by window fitters
- Draughts coming in around windows and doors
For site and facilities teams at buildings such as East Hoathly CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
