New build mastic in Canary Wharf, done properly
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference, because that is what rushed new-build sealant usually lacks. If you are dealing with gaps between new skirting and floors and shower seals failing in the first year or two, we can help, on kitchens, show homes and plot handovers alike.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
There’s a 12-month guarantee on every job.

New homes and floors in Canary Wharf
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. 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.
Canary Wharf is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

How it works
On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take a few hours in a single home. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Canary Wharf. It helps if you can point us to a visitor permit or a bay close to the door.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before

Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Canary Wharf: your questions answered
Is parking an issue for new build mastic in Canary Wharf?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can you help a landlord with a rental near Canary Wharf station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you when we finish.
Can you match the sealant colour to my new kitchen or bathroom?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Is it worth resealing while the house is still settling?
Where water is getting through, don’t wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
Do you come to Canary Wharf?
Yes. We work in Canary Wharf, as part of our work across South East England, London and Scotland. For a quote, ring 0345 464 0079 or drop us an email.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Landlord and commercial work in Canary Wharf
For anyone letting property in or around Canary Wharf, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
Landlords and agents in Canary Wharf can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Canary Wharf.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
Why us?
- Approved under the ARBOMaster scheme
- Colour picked to suit the job
- We’re fully insured
- More than 20 years in sealant work

Do you need new build mastic in Canary Wharf?
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that cannot keep up splits.
Most people get in touch after spotting something like this:
- Cracks appearing as a new home settles
- Gaps between new skirting and floors
- Sealant applied over dusty or wet surfaces
- Worktop and upstand sealant coming away
For new homes near Canary Wharf station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- Is the old sealant removed completely?
- What the cure time is
- Who does the work, and how experienced they are
- What insurance they hold
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.
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.
What affects the quote in Canary Wharf
Every job gets its own quote. These are the things that affect it:
- The number and length of the joints
- Mould in or behind the old joints
- Working hours on commercial sites
- How many areas need sealing
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
What we need to know
To make quoting easier, let us know:
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
Asking for a quote is easy: tell us what needs doing and where. A few photos by email make the job easier to understand, and we will come back to you with a quote.
