How we handle sand mastic in Enfield Chase
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on period & listed homes, brick reveals and timber door frames, and common reasons people get in touch are mastic that needs renewing before redecorating and modern sealant on a period surround.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Enfield Chase.
You get a one-year guarantee, the same in Enfield Chase as everywhere else we work.

How the visit works
We keep the work tidy and contained to the joints we are treating. The job generally takes anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Before we arrive
- Move anything stored near the joints
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children

Enfield Chase: your questions answered
Is parking a problem for a job in Enfield Chase?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
I let a flat near Enfield Chase station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
How long does the job take?
That depends on the amount of work, but as a guide it takes a few hours for a single window, longer for several. We will tell you when we quote.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
How much does sand mastic cost in Enfield Chase?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or drop us an email and tell us what needs doing and where.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Are you fully insured?
Yes. We are fully insured.
Do you need sand mastic in Enfield Chase?
Timber frames move with the seasons. That movement opens up the mastic joint over time.
People normally contact us when they notice something like this:
- Mastic dropping out of the joint
- Cracked mastic round a front door frame
- Mastic that needs renewing before redecorating
- Modern sealant on a period surround
As a London address, Enfield Chase can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Why act early in Enfield Chase
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.
What you get with us
- Homes, businesses and hotels
- An ARBOMaster approved applicator
- Quality sealants from Arbo and Everbuild
- Rated 4.9 stars on Google

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What sand mastic looks like in Enfield Chase
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In a converted house or block, who looks after the windows depends on the lease, so check that before you book.
If you live in an older home near Church of St Mary Magdalene, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Chase Side Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
