How the visit works
On the day, we start by going over the job with you. We protect the surfaces around the joints before work begins. The work generally takes a few hours for a single window, longer for several. Parking in a town like Waltham Abbey is normally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before

Advice
How we handle sand mastic in Waltham Abbey
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We work on period & listed homes, brick reveals and stone surrounds, and people most often call us about wind and rain getting in round a sash window and silicone on a period window that looks wrong.
Plenty of homes in a town like Waltham Abbey have had conservatories, patio doors or new windows added over the years. Every addition brings more joints, each wearing at its own pace. Leaks usually start at a sill, a frame head or a glazing joint.
Every job is covered by a one-year guarantee, wherever you are in Essex.

Frames and glazing around Waltham Abbey
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Forty Hall (about 3.6 miles west) are a reminder that the area around Waltham Abbey has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Waltham Holy Cross Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Waltham Cross station, cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Waltham Abbey Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

What affects the quote in Waltham Abbey

- The old material and how stubborn it is
- The number of rooms or windows
- The size of the job
- The product the joint needs
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Surface by surface
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Masonry that needs repairing
- Sash cords, weights and draught-proofing of the sashes
- Timber that has rotted
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Sash and case windows
- Period & listed homes
- Brick reveals
- Tenement windows
- Stone surrounds
- Timber door frames
Looking after it afterwards
Aftercare is simple:
- Keep sills and gutters clear so water drains away
- Find out about consent before window work on a listed home
- Get any rot dealt with first
- Don’t paint over the new mastic
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.

From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Your questions about sand mastic in Waltham Abbey

Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll talk you through it.
How long does sand mastic take to go off?
The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.
What guarantee comes with the work?
You get our 12-month guarantee to all our work.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.
