How we handle window mastic in Hook Common
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you have sealant in the wrong colour for the frame and draughts coming in around windows and doors, we can put it right, on patio & French doors, timber windows & doors and window sills alike.
Somewhere as small as Hook Common, 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.
Big or small, it’s backed by our one-year guarantee in Hook Common and across Hampshire.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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.
Frames and glazing around Hook Common
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to 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. Managing a site like Hook Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Other services in Hook Common
Different surfaces, different methods

Soft or rotten wood can’t be sealed successfully. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.
Composite doors
Front doors take the weather head on. We pay most attention there.
Do you need window mastic in Hook Common?
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.
Signs it’s time to call us include:
- Old mastic that has gone black or come away
- White mastic on grey or black frames
- Rushed sealant from a window installation
- Cracked or shrunken mastic around the frame
For landlords with property near Hook station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before you book
- The length of the guarantee
- Which colour the sealant will be
- What happens if the job turns out different
- Whether all the old sealant comes out first
How the visit works
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a morning for a couple of windows and a door in most cases. For a village or hamlet like Hook Common, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Mention any parking rules near the property
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can

Your questions about window mastic in Hook Common
Can you help a landlord with a rental near Hook station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Can you do window mastic in Hook Common?
Yes. We work across London and the South East, and Hook Common is part of that. Just call 0345 464 0079 or email us with a few details of the job.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where do you work from?
We work from Crawley. We cover Hook Common and the rest of Hampshire, along with the rest of our area.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

How to look after the new joints
After the cure time, these simple habits help:
- Clean frames with a soft cloth and soapy water
- Check the mastic once a year
- Air rooms to keep condensation down around windows
- Do not paint over the silicone
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
