How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes most of a day for a typical house, less for a few frames. For a village or hamlet like Binley, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
Before we arrive
- Clear the area around the work
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can

How we handle window mastic in Binley
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on timber windows & doors, aluminium frames and composite doors, and the jobs we see most are sealant in the wrong colour for the frame and leaking joints at the ends of sills.
Somewhere as small as Binley, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Big or small, you get the same 12-month guarantee.

Signs you need window mastic in Binley
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. Backing rod sets the right depth.
If you can see any of these, it’s time to have the joints looked at:
- Cracked or shrunken mastic around the frame
- Gaps between the frame and the inside reveal
- Untidy mastic left by window fitters
- Black, perished sealant on frames
Historic houses such as Highclere Castle, about 3.8 miles north-east, show how far back building around Binley goes, and older homes nearby need a sealant that suits their walls.

Binley homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Highclere Castle (about 3.8 miles north-east) are a reminder that the area around Binley has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you let a flat or house near Whitchurch (Hampshire) station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

FAQs for Binley
Is Binley within the area you cover?
Yes, smaller places are covered as well as towns. 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 Whitchurch (Hampshire) station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Can you do upstairs windows?

Where do you work from?
Mr Mastic is based in Crawley. We cover Binley and the rest of Hampshire.
How long will my window job take?

Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Can I paint over the new sealant?
Silicone generally won’t take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How the job changes by surface
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Looking after it afterwards
After the cure time, these simple habits help:
- Keep timber frames painted
- Check the mastic once a year
- Keep paint off silicone joints
- Ventilate rooms so frames don’t stay wet inside
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
Landlords, agents and businesses in Binley
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Why act early in Binley
Working on frames from a ladder with a sealant gun is not easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In a small place like Binley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
