Questions from Redbridge
Will you come out to Redbridge?
Yes, Redbridge is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Chadwell Heath station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
How long does sand mastic take to go off?
A skin forms quite soon, but full hardening takes longer. We’ll tell you what to expect for your job.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
About our sand mastic in Redbridge
We work across Redbridge renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. If you are dealing with old cement repairs round a window that have failed and a silicone bead on a sash window that spoils the look, we can put it right, on timber door frames, period & listed homes and tenement windows alike.
Around Redbridge, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Your job is guaranteed for a year, as with all our work.

What the job involves on each surface
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.

How we quote for sand mastic
We do not publish a price list. What we look at:
- Any mould that needs treating
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
What to tell us when you ask for a quote:
- The problem you’ve noticed
- Where the job is, and your postcode
- The rough size of the job
- Whether it has been sealed before
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you are ready, phone 0345 464 0079 or send us an email.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a single window, longer for several. For a village or hamlet like Redbridge, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

When something else is needed
New sealant can’t fix everything, and we’ll tell you before any work starts. Sealant won’t put right:
- Planning or listed building consent (your local planning authority decides)
- Timber that has rotted
- Putty and glazing repairs
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Sash and case windows
- Brick reveals
- Timber door frames
- Tenement windows
- Stone surrounds
- Period & listed homes
Why deal with it now?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. Older cottages and farmhouses around Redbridge can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Do you need sand mastic in Redbridge?
Timber frames move with the seasons. That movement opens up the mastic joint over time.
If you can see any of these, it’s time to have the joints looked at:
- Mastic worn away on windows facing the weather
- Wind and rain getting in round a sash window
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic that needs renewing before redecorating
If you look after a building such as Oasis Academy Pinewood, the mastic around its windows and doors needs looking after like any other building’s.

- What the quote includes, VAT included or not
- Is the old sealant removed completely?
- What insurance they hold
