New build mastic for homes and businesses in Collier Row
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you have sealant applied over dusty or wet surfaces and cracked sealant around new window and door frames, we can put it right.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
All our work comes with our 12-month guarantee.

The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for most snagging lists, longer for a run of plots. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Collier Row. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
- Move anything stored near the joints

Advice
Why it’s worth doing now in Collier Row
A hairline gap at a skirting can wait, but a leaking seal cannot. If you are unsure which you have, phone 0345 464 0079 or email us with photos. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Collier Row, the repair is bigger than a sealant job.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
Why book with us
- Any old sealant cut out fully, not covered over
- Fully insured
- Homes, businesses and hotels
- 4.9 on Google from 180+ five-star reviews
What we cannot put right
Before booking, it’s worth knowing the limits too:
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with
- Settlement cracks that need a surveyor
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
What we seal

New build mastic around Collier Row
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
As a London address, Collier Row can be tricky for parking: let us know about parking bays, permits or a driveway. For new homes near Romford station, it’s worth checking the sealant early, while snags are still fresh.

What affects the cost of new build mastic
The price is agreed before any work begins. It’s based on:
- How easy the joints are to reach
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- The type of sealant required
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- Where the job is, and your postcode
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we will come back to you with a quote.
Different surfaces, different methods
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Watch for new gaps as the house dries out
- Resist patching a failed seal with a tube from the DIY shop
- Wipe joints with warm soapy water
- Keep water off fresh sealant until it has cured
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
