Window mastic for homes and businesses in Breach
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re fully insured ARBOMaster approved applicators, and we give a 12-month guarantee on the work. We’re often asked to deal with cracked internal joints between frame and plaster and leaking joints at the ends of sills, across uPVC windows, window sills and aluminium frames.
Homes in small places like Breach often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

What window mastic looks like in Breach
With historic houses such as Acrise Place (about 3.4 miles south) nearby, there’s older building stock in the area around Breach 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. 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.

Leave it or put it right?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Where a wall is exposed, as many are in small places like Breach, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why Breach clients choose us
- Anti-fungal sanitary silicone in wet areas
- 20+ years of sealant experience
- Domestic, commercial and hotel work
- White, clear, grey or coloured to suit, where the product allows

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Landlords, agents and businesses in Breach
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes most of a day for a typical house, less for a few frames. Somewhere as small as Breach, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Getting ready for the visit
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can

Your questions about window mastic in Breach
Do you work for landlords with property near Snowdown station?
Yes. We work for landlords and letting agents as well as homeowners. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Is Breach within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
How long before the joint can be used?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
Will new mastic stop draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
How long does it take to reseal the windows on a house?
The work takes a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.

What we’re called out for in Breach
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
The problems people usually mention when they call are:
- Damp patches on the reveal after heavy rain
- Mastic that is falling out in pieces
- Gaps where the sill meets the wall
- Gaps between the frame and the inside reveal
Letting a property close to Snowdown station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before booking
- Is the old sealant removed completely?
- Whether you can choose the colour
- What preparation is included
- Whether the sealant suits the joint
