Specialist sand mastic for Poplar: careful preparation, the right product and tidy work. Call for a quick quote.
- Gaps round a timber door in stone or brick
- Weathered mastic on the most exposed windows
- Draughts and rain around sash boxes
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Have rotten timber repaired before new mastic goes in
- Check the mastic when you check the paintwork
- Keep modern sealant off the mastic
- Go gently near the mastic when preparing windows
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Sand mastic in Poplar, done properly
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on stone surrounds, period & listed homes and brick reveals, and people most often call us about gaps where the frame meets the masonry and patchy fillers round a sash window.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

FAQs for Poplar
Is Poplar in your area for sand mastic?
Yes, Poplar is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Can you help a landlord with a rental near Canary Wharf station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Is consent needed for window work on a listed home?
Check with your local planning authority. They decide whether consent is needed.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.
When will the new mastic be hard?
Not straight away. It skins first and hardens fully later and we will give you an idea for your job.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What should I tell you?
Tell us what needs doing and where, plus pictures if you have them. If we need more, we’ll ask.
How long does sand mastic take?
It depends on the size of the job, but most jobs take a few hours per window, depending on the condition of the joints. We’ll give you a better idea when we quote.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Whether work needs listed building consent
- Sashes that need overhauling
- Damaged stone surrounds
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before booking.
Where we work in Poplar
- Stone surrounds
- Period & listed homes
- Sash and case windows

When to call us in Poplar
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
If you can see any of these, it’s time to have the joints looked at:
- Failed mastic on an exposed elevation
- Mastic dropping out of the joint
- Cracked mastic round a front door frame
- A silicone bead on a sash window that spoils the look
If you look after a building such as Tower Hamlets College, its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- Who turns up on the day
- How long the guarantee is
- Is the old sealant removed completely?
- What insurance they hold

Advice
Frames and glazing around Poplar
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Queen's House (about 1.9 miles south) nearby, there’s older building stock in the area around Poplar 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.
As a London address, Poplar can be tricky for parking: let us know about parking bays, permits or a driveway. If you live in an older home near St Peter's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What the job involves on each surface
Stone surrounds
The stone is treated with care while raking out the old mastic.
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
