North Holmwood homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Polesden Lacey (about 3.8 miles north-west) nearby, there’s older building stock in the area around North Holmwood as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Dorking West station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like St John's Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

About our window mastic in North Holmwood
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you have untidy mastic left by window fitters and damp patches on the reveal after heavy rain, we can put it right.
Around North Holmwood, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Leave it or put it right?
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Homes in smaller places like North Holmwood can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Keep timber frames painted
- Wipe condensation off the frames
- Don’t use solvent cleaners on the joint
- Keep paint off silicone joints
Most silicone sealants won’t take paint, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Common problems we fix in North Holmwood
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That is what backing rod is for.
Any of these means the joints need attention:
- Old mastic that has gone black or come away
- Cold air getting in at the frame edge
- Gaps where the sill meets the wall
- Rain getting in at the frame or under the sill
Homes close to Church of St John the Evangelist include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the visit works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for a handful of frames, longer for a whole house from start to finish. For a job in North Holmwood, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, 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.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- Any mould that needs treating
- How many areas need sealing
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
