Window & door mastic in Bow Brickhill, Milton Keynes
Window mastic in Bow Brickhill from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Old mastic that has gone black or come away
- Damp patches on the reveal after heavy rain
- Cracked or shrunken mastic around the frame
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Keep drainage slots and sill grooves clear
- Keep solvents and bleach off the sealant
- Paint up to the joint, not over it
- Keep paint and stain on wooden frames in good order
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
How we handle window mastic in Bow Brickhill
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. Common call-outs are for white mastic on grey or black frames and hard, cracked sealant around windows, on aluminium frames, timber windows & doors and patio & French doors.
In a village or hamlet like Bow Brickhill, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

Is it OK to seal over old sealant?

Can you get sealant to suit coloured frames?
Generally, yes. Tell us the frame colour when you get in touch and we will match it as closely as we can.
How the visit works
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 anything from an hour or two to a full day, depending on how many frames there are. In a small place like Bow Brickhill, access is normally the main thing to plan. 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.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit

What affects the cost of window mastic
We don’t publish a price list, because jobs vary so much. What we look at:
- The number of rooms or windows
- Working hours on commercial sites
- Mould in or behind the old joints
- The product the joint needs
What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts.
What we need to know
Before you ask for a quote, have a think about:
- Roughly how big the job is
- The problem you’ve noticed
- Any access issues, like height or stairs
- Where the property is
To get a quote, ring 0345 464 0079 or email us and tell us where the job is and what the problem looks like. We will give you a clear quote before any work starts.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
What happens if it’s left?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. In a small place like Bow Brickhill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

- Cracked sealant at the sill ends
- White mastic on grey or black frames
For landlords with property near Bow Brickhill station, renewing tired window mastic between tenants heads off draught and damp complaints.

What the job involves on each surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
Frames and glazing around Bow Brickhill
The South East is one of 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 Bletchley Park (about 2.6 miles west) nearby, there’s older building stock in the area around Bow Brickhill 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.
In the older streets around Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Bow Brickhill CofE VA Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
