How we handle window mastic in West Tisted
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on timber windows & doors, aluminium frames and uPVC windows, and people most often call us about gaps between the frame and the inside reveal and whistling draughts around closed windows.
Homes in small places like West Tisted often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Damp problems in the wall away from the window
- Soft or decayed wood in the frame
- A door that needs adjusting, rehanging or new seals
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.

Aftercare tips
A little care helps the new joints last. We recommend:
- Keep paint and stain on wooden frames in good order
- Avoid blasting the frames with a pressure washer
- Paint up to the joint, not over it
- Use gentle cleaners on frames and sealant
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just call 0345 464 0079 or send us an email.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
Common problems we fix in West Tisted
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
The problems people normally mention when they call are:
- Untidy mastic left by window fitters
- A bead that does not match the frame
- Cracked sealant at the sill ends
- Old mastic that has gone black or come away
In and around West Tisted, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Your questions about window mastic in West Tisted
Can you do window mastic in West Tisted?

Is window mastic in West Tisted guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
Can you seal the gap between the frame and the plaster indoors?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a few frames, or a day or more for a whole house. Somewhere as small as West Tisted, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- 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.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints

Advice
How we quote for window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The amount of work
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- Whether there’s mould to deal with
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
Helping us quote
Before you ask for a quote, have a think about:
- If someone has resealed it before
- The address or postcode of the job
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand.
Why it’s worth doing now in West Tisted
Choosing the product is half the job. Interior caulk and bathroom silicone are not made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Around West Tisted, 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 the work is at height. Your quote takes all of that into account.
Why choose Mr Mastic in West Tisted
- A choice of colours where the product allows
- A 12-month guarantee on all work
- We leave the area clean and tidy
- Full insurance on every job

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Window mastic in West Tisted: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Hinton Ampner House (about 3.6 miles west) nearby, there’s older building stock in the area around West Tisted 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.
If you live in an older home near Church of St Mary Magdalene, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
