Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Window mastic in Poundon, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. If you are dealing with draughty joints inside around the window and draughts coming in around windows and doors, we can put it right, on patio & French doors, timber windows & doors and window sills alike.
In a village or hamlet like Poundon, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
A one-year guarantee comes as standard.

Questions from Poundon
I let a flat near Bicester North 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 we start.
Do you cover Poundon for window mastic?
Yes. Our work covers London and the South East, and Poundon is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
Will resealing my frames help with draughts?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames generally suit brown.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
How many windows can you do in a day?
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 information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Why act early in Poundon
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 Poundon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear quote before any work starts.

Windows and doors in Poundon
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Claydon House (about 4.5 miles east) nearby, there’s older building stock in the area around Poundon as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Bicester North station, renewing tired window mastic between tenants heads off draught and damp complaints.

Different surfaces, different methods
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Draughts through the window seals rather than the frame
- Broken hinges, locks or handles
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Window sills
- Timber windows & doors
- Aluminium frames
- uPVC windows
- Composite doors
- Patio & French doors
Should I try it myself first?
If you are set on DIY, put the effort into 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.
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.

Signs you need window mastic in Poundon
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.
These are the problems we are asked about most:
- Sealant in the wrong colour for the frame
- Whistling draughts around closed windows
- Mastic that has split away from the wall
- Rushed sealant from a window installation
Claydon House, about 4.5 miles east, is one of the historic houses in the wider area around Poundon, and older homes nearby need a sealant that suits their walls.
