Window & door mastic in Warren Corner, Surrey
Problem with your window and door frames in Warren Corner? We cut out the old, prepare the joints and apply the right sealant.
- Cracked sealant at the sill ends
- Mastic that has split away from the wall
- Draughty joints inside around the window
Window mastic for homes and businesses in Warren Corner
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. Typical jobs include mastic that’s falling out in pieces and draughty joints inside around the window, across patio & French doors, uPVC windows and window sills.
In a village or hamlet like Warren Corner, 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.
A 12-month guarantee comes as standard.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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 does not work out, we can still put it right.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep paint and stain on wooden frames in good order
- Keep paint off silicone joints
- Air rooms to keep condensation down around windows
- Do not use solvent cleaners on the joint
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
Questions from Warren Corner
I let a flat near Farnham station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Will you come out to Warren Corner?
Yes, Warren Corner is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you will get one quote.
How long will my window job take?
That depends on the number of frames, how they’re reached and the state of the old mastic. You will know the timing when we quote.

Warren Corner homes and the weather
With historic houses such as Farnham Castle (about 2 miles south-east) nearby, there’s older building stock in the area around Warren Corner 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. 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.
If you look after a building such as Crondall Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near St Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Farnham station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

- Draughts through the window seals rather than the frame

How it works
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take most of a day for a typical house, less for a few frames. Somewhere like Warren Corner needs a little journey planning: 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 look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
How to prepare
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts

Different surfaces, different methods
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. If we find rot, we’ll tell you before going ahead, as a joiner will need to deal with it.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
