When something else is needed
Some problems need a builder, plumber or other trade rather than us:

About our window mastic in Hoddesdon
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. If you have a bead that doesn’t match the frame and hard, cracked sealant around windows, we can put it right.
Hoddesdon mixes older streets, where windows have often been replaced, with newer estates fitted with uPVC. In every case, the joint between frame and wall is what keeps water out.
You get a 12-month guarantee, the same in Hoddesdon as everywhere else we work.

Why it’s worth doing now in Hoddesdon
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.
Doing several joints on one visit is usually more efficient than separate visits. You will get one clear quote for the whole job.

Surface by surface
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
What we do, step by step
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a morning for a couple of windows and a door, including the tidy-up. For a job in Hoddesdon, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- 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
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises

Advice
When to call us in Hoddesdon
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
These are the problems we are asked about most:
- Gaps between the frame and the inside reveal
- Rushed sealant from a window installation
- Cracked or shrunken mastic around the frame
- Damp patches on the reveal after heavy rain
Letting a property close to Broxbourne station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Rainfall in the South East is lower than in much 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 Sheredes School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Catherine & St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
