Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Window mastic in Weybridge, done properly
Around Weybridge we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Typical jobs include gaps where the sill meets the wall and cracked internal joints between frame and plaster, across timber windows & doors, patio & French doors and aluminium frames.
Plenty of homes in a town like Weybridge have had conservatories, patio doors or new windows added over the years. Each one adds more joints to look after, and those joints age at different rates. Sills, frame heads and glazing joints are where leaks usually start.
Every job is covered by our 12-month guarantee.

Leave it or put it right?
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. In a family home in Weybridge, a failed seal around a bath or a frame lets water into places you can’t see, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.

What the job involves on each surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Signs you need window mastic in Weybridge
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. That’s what backing rod is for.
The problems people usually mention when they call include:
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
- Leaking joints at the ends of sills
- Draughty joints inside around the window
Schools such as St James CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Aftercare tips
After the cure time, these simple habits help:
- Keep timber frames painted
- Walk round the house once a year and look at the joints
- Wash the frames with mild soapy water
- Keep drainage slots and sill grooves clear
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
What happens on the day
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes most of a day for a typical house, less for a few frames in most cases. A visit in Weybridge needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Mention any tricky access
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can

Advice
Frames and glazing around Weybridge
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 Byfleet Manor (about 2.9 miles south) nearby, there’s older building stock in the area around Weybridge as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you let a flat or house near Weybridge station, renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around United Reform Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
