Window mastic in Bashley
Homes in Bashley have every kind of window: uPVC, aluminium, timber and composite, 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, uPVC windows and composite doors, and people most often call us about old mastic that has gone black or come away and gaps left after new windows were fitted.
Around Bashley, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, in Bashley and everywhere else we cover.

What affects the quote in Bashley
The price is agreed before any work begins. It’s based on:
- Working hours on commercial sites
- Access and height
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. In a small place like Bashley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

Bashley questions
Does the coastal weather in Bashley affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can you help a landlord with a rental near New Milton station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can I paint over the new sealant?
Silicone generally will not take paint. Let us know beforehand, and we’ll use a paintable product where it suits.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What the job involves on each surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
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
New sealant can’t fix everything, and we’ll tell you before work begins. Sealant will not put right:
- A door that needs adjusting, rehanging or new seals
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Soft or decayed wood in the frame
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.
Surfaces we seal
- Window sills
- Patio & French doors
- Timber windows & doors
- Aluminium frames
- uPVC windows
- Composite doors
Do you need window mastic in Bashley?
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
Signs it’s time to call us include:
- Rain getting in at the frame or under the sill
- Black, perished sealant on frames
- Gaps left after new windows were fitted
- Sealant in the wrong colour for the frame
For site and facilities teams at buildings such as Ballard School, larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- What happens if they find a problem under the old sealant
- What product goes in the joint
- Whether you can choose the colour
- The length of the guarantee
The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a handful of frames, longer for a whole house. In a small place like Bashley, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts

Related advice
Windows and doors in Bashley
Bashley is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. With historic houses such as Highcliffe Castle (about 3.5 miles south-west) nearby, there’s older building stock in the area around Bashley as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you let a flat or house near New Milton station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near St John, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
