Window mastic in Hipley, done properly
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. Where the air is getting in through the window itself, we’ll say so. Common call-outs are for water coming in at the bottom corners of a door and mastic that’s falling out in pieces, across window sills, patio & French doors and composite doors.
Mastic can only go onto a dry, clean joint, so window work in Hipley is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Is Hipley within the area you cover?
Yes, Hipley is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can new window sealant be painted?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Mention any painting plans before work begins.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
What information do you need?
Tell us what needs doing and where, with pictures by email if possible. We’ll ask anything else we need to know.
Can you do upstairs windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.
What window mastic looks like in Hipley
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.
Managing a site like Newtown Soberton Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of the Holy Trinity, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What’s near Hipley

Why act early in Hipley
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we’ll tell you. Older cottages and farmhouses around Hipley can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

What we do, step by step
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from an hour or two to a full day, depending on how many frames there are in most cases. In a small place like Hipley, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- 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.
- 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
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints

Common problems we fix in Hipley
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
Most people get in touch after spotting one of these:
- A bead that does not match the frame
- Draughty joints inside around the window
- Cracked sealant at the sill ends
- Cracked or shrunken mastic around the frame
Rented homes near Portchester station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Aftercare tips
So the new joints stay in good condition:
- Clear any debris from frame drain holes
- Avoid harsh chemicals near the mastic
- Keep paint and stain on wooden frames in good order
- Paint up to the joint, not over it
Try not to touch the new joint while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
