How we handle window mastic in South Holmwood
Homes in South Holmwood have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on timber windows & doors, uPVC windows and aluminium frames, and the jobs we see most are cracked sealant at the sill ends and mastic that has split away from the wall.
Somewhere as small as South Holmwood, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Each job carries a 12-month guarantee, large or small.

South Holmwood homes and 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. Historic houses like Polesden Lacey (about 5 miles north-west) are a reminder that the area around South Holmwood has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For landlords with property near Holmwood station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Church of St Mary Magdalene, the joint between an old wall and a newer frame is generally the first place rain gets in.

What else we do in South Holmwood
DIY sealant or a professional job?
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 fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. Somewhere like South Holmwood needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Before we arrive
- Keep children and pets away from the work area
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints

Do you need window mastic in South Holmwood?
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
If you can see any of these, it’s time to have the joints looked at:
- Untidy mastic left by window fitters
- Hard, cracked sealant around windows
- Old mastic that has gone black or come away
- Draughts coming in around windows and doors
For site and facilities teams at buildings such as The Priory CofE Voluntary Aided School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- Whether they’re fully insured
- How much experience the applicator has
- What preparation is included
- Is the old sealant removed completely?
Looking after it afterwards
So the new joints stay in good condition:
- Air rooms to keep condensation down around windows
- Do not use solvent cleaners on the joint
- Repaint timber before it’s bare
- Keep drainage slots and sill grooves clear
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
