Window mastic for homes and businesses in Mundon
From a single sill to a whole house of windows, you’ll get a clear quote before we start. Just ring 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached for window mastic in Mundon. We are often asked to deal with draughty joints inside around the window and rushed sealant from a window installation, across window sills, composite doors and timber windows & doors.
Homes in small places like Mundon 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.
All of our work is guaranteed for twelve months, in Mundon and everywhere else we cover.

Quotes for window mastic in Mundon
Jobs vary more than people expect. What affects the quote:
- The amount of work
- The number of rooms or windows
- Any working-time requirements on site
- Whether there’s mould to deal with
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Photos by email, if that is easy
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Don’t use solvent cleaners on the joint
- Look round the frames every year or so
- Keep jet washers away from the mastic
- Wash the frames with mild soapy water
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
For landlords and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

What happens if it’s left?
Resealing frames is a short job: the visit takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. In a small place like Mundon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Frames and glazing around Mundon
Mundon is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. 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.
For landlords with property near North Fambridge station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near St Mary's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How it works
We keep the work tidy and contained to the joints we are treating. The job normally takes anything from an hour or two to a full day, depending on how many frames there are, and we explain the cure time before we leave. For a village or hamlet like Mundon, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
