Epping Green: your questions answered
Do you work for landlords with property near Roydon station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Epping Green?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
How long should I leave it?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
How we handle window mastic in Epping Green
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. If you have mastic that’s falling out in pieces and cold air getting in at the frame edge, we can help.
Somewhere as small as Epping Green, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clear any debris from frame drain holes
- Air rooms to keep condensation down around windows
- Do not use solvent cleaners on the joint
- Check the mastic once a year
Silicone cannot usually be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
How the job changes by surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that, where a rigid one would crack.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Windows and doors in Epping Green
Historic houses like Hill Hall (about 4.9 miles south-east) are a reminder that the area around Epping Green has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Roydon station, renewing tired window mastic between tenants heads off draught and damp complaints.

How it works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes most of a day for a typical house, less for a few frames. For a village or hamlet like Epping Green, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
- Mention any tricky access

Advice
Can I do it myself?
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
When to call us in Epping Green
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Common reasons people contact us include:
- Damp patches on the reveal after heavy rain
- Gaps left after new windows were fitted
- Cracked sealant at the sill ends
- Whistling draughts around closed windows
Managing a site like Epping Upland CofE Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- Whether all the old sealant comes out first
- Are they insured?
- Which sealant they’ll use, and why
- How much experience the applicator has
Landlord and commercial work in Epping Green
Landlords and letting agents in Epping Green can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Honest limits
We will always be straight with you, so here’s what new sealant won’t do:
- Faulty window hardware
- Damp problems in the wall away from the window
- Worn gaskets, brush seals or a door that has dropped
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.
