For landlords and businesses
We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
How we handle window mastic in Wyatt's Green
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you are dealing with old mastic that has gone black or come away and sealant in the wrong colour for the frame, we can put it right.
Somewhere as small as Wyatt's Green, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
There’s a 12-month guarantee on every job, large or small.

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Condensation trapped between the panes
- Draughts through the window seals rather than the frame
- Damp problems in the wall away from the window

Wyatt's Green homes and the weather
With historic houses such as Ingatestone Hall (about 3.5 miles east) nearby, there’s older building stock in the area around Wyatt's Green as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Doddinghurst Infant School? Then 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 All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Can I do it myself?
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.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Why deal with it now?
The work is quick compared with the damage it prevents: it takes a few hours for a handful of frames, longer for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Wyatt's Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Keep drainage slots and sill grooves clear
- Keep paint and stain on wooden frames in good order
- Ventilate rooms so frames do not stay wet inside
- Paint up to the joint, not over it
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.

The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Wyatt's Green, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- 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.
How to prepare
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on

Do you need window mastic in Wyatt's Green?
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Signs it’s time to call us include:
- Damp patches on the reveal after heavy rain
- Cold air getting in at the frame edge
- Gaps between the frame and the inside reveal
- Gaps left after new windows were fitted
For landlords with property near Shenfield station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
