The problems people usually mention when they call are:
- Gaps where the frame meets the masonry
- Patchy fillers round a sash window
- Modern sealant on a period surround
- Draughty sash windows at the surround
Canary Wharf is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

About our sand mastic in Canary Wharf
Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead, and we will talk through which suits your home. We work on stone surrounds, brick reveals and period & listed homes, and common reasons people get in touch are mastic round period door frames that has failed and cement or filler used on old window joints that has cracked.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
There’s a 12-month guarantee on every job, large or small.

Surface by surface
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. It’s renewed by hand.
What affects the cost of sand mastic
Your quote is based on your job. We take into account:
- The old material and how stubborn it is
- The product the joint needs
- The size of the job
- Mould in or behind the old joints
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- The type of property
- How many joints, rooms or windows are involved
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, call 0345 464 0079 or drop us an email.
What happens on the day
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to a full day, depending on how many windows. In Canary Wharf, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints

FAQs for Canary Wharf
Do you work for landlords with property near Canary Wharf station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Can parking be tricky for a visit in Canary Wharf?
Parking in Canary Wharf, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for listed or conservation-area properties.
What guarantee comes with the work?
Every job comes with our one-year guarantee, and we are fully insured.
How long does sand mastic take to harden?
It takes a while. The skin forms first, and the full set comes later, and we’ll tell you what to expect.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or drop us an email.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

What else we do in Canary Wharf
Why act early in Canary Wharf
Filling over old, loose mastic does not last. We remove the loose material first so the new mastic stays put. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Canary Wharf, the repair is bigger than a sealant job.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Canary Wharf homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
Letting a property close to Canary Wharf station? Then any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as St Peter's Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
