What happens if it’s left?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. Where a wall is exposed, as many are in small places like Crouch, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

How we handle window mastic in Crouch
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. If you’re dealing with mastic that has split away from the wall and white mastic on grey or black frames, we can help, on composite doors, patio & French doors and aluminium frames alike.
Somewhere as small as Crouch, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Each job carries a 12-month guarantee, whatever its size.

What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Mould in or behind the old joints
- The product the joint needs
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email and we will talk you through it.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- The rough size of the job
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, ring 0345 464 0079 or email us.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Windows and doors in Crouch
With historic houses such as Belmont House and Gardens (about 4.2 miles west) nearby, there’s older building stock in the area around Crouch 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’s traditional sand mastic. 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.
If you let a flat or house near Selling station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For an older house near a landmark such as Church of St Peter and St Paul, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Boughton-under-Blean and Dunkirk Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Crouch: your questions answered
Will you come out to Crouch?
Yes. Crouch is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Selling station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
Can you do upstairs windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote and we will plan for it.
Different surfaces, different methods
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
Composite doors
A composite door normally sits in a plastic outer frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Landlords, agents and businesses in Crouch
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Avoid blasting the frames with a pressure washer
- Walk round the house once a year and look at the joints
- Keep paint off silicone joints
- Keep timber frames painted
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or email us.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take a morning for a couple of windows and a door. Somewhere as small as Crouch, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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 parking rules near the property
- Mention any tricky access
- Clear items away from the joints we are working on
