Frames and glazing around Brook
Historic houses like Landford Manor (about 4.1 miles north) are a reminder that the area around Brook has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
Landford Manor, about 4.1 miles north, is one of the historic houses in the wider area around Brook, and older homes nearby need a sealant that suits their walls.

How we handle window mastic in Brook
Around Brook we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We are often asked to deal with rushed sealant from a window installation and draughts coming in around windows and doors, on composite doors, window sills and timber windows & doors.
In a village or hamlet like Brook, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Every job comes with a one-year guarantee, wherever you are in Hampshire.

How we quote for window mastic
We don’t publish a price list, because jobs vary so much. The quote depends on:
- How many areas need sealing
- Whether old sealant or filler has to be cut out
- The size of the job
- Mould in or behind the old joints
Combining jobs into one visit is usually more efficient than separate visits. We will give you a clear price for the lot.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- How we’d reach the joints
- Whether it’s a home or a business
- Pictures of the joints, sent by email
- What’s wrong with the joints now

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep paint off silicone joints
- Keep drainage slots and sill grooves clear
- Do not aim a pressure washer at the joints
- Keep paint and stain on wooden frames in good order
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
Why deal with it now?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Around Brook, older homes often have timber in their floors and frames, where water from a failed joint can cause rot 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. Your quote takes all of that into account.

- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.

Common problems we fix in Brook
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.
It’s worth asking for a quote if you see:
- Mastic that has split away from the wall
- Whistling draughts around closed windows
- Gaps where the sill meets the wall
- Water coming in at the bottom corners of a door
Letting a property close to Ashurst New Forest station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
What to look for in a quote
- How much experience the applicator has
- Whether all the old sealant comes out first
- What the quote includes, VAT included or not
- How long the guarantee is

What the job involves on each surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones aren’t used, as they can attack some metals. We use a neutral-cure product.
