Noel Park New Build Mastic
New build mastic across Noel Park and nearby, with old sealant always removed completely and a one-year guarantee.
- Skirting joints opening in the first winter
- Frame joints opening as the plaster dries
- Shower seals failing in the first year or two
Surface by surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing to keep callbacks down.
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
New build mastic in Noel Park, done properly
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly rather than sitting on a layer of grit. We’re often asked to deal with untidy sealant flagged on a snagging list and cracked caulk along new skirting, across plot handovers, windows & doors and kitchens.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

What we can’t put right
Sealant is not the answer to every problem, and we’ll tell you before we start. It will not solve:
- A tray or bath that isn’t properly supported, until it’s fixed
- Disputes or warranty claims with your builder
- Cracking that points to a structural problem
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Clean sealant with mild detergent, not abrasives
- Use the extractor fan every time you shower
- Don’t wait for the house to settle if water is getting through
- Keep pictures and emails about snagging items
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.
How we quote for new build mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Mould in or behind the old joints
- Access and height
- Any working-time requirements on site
- The old material and how stubborn it is
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- The rough size of the job
- Whether it has been sealed before
- What’s wrong with the joints now
- Photos by email, if that’s easy
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved and send you a clear quote.
Why act early in Noel Park
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a flat in Noel Park, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.
Why book with us
- Tidy, careful work
- Sealant colour chosen to suit
- A 12-month guarantee on all work
- Approved under the ARBOMaster scheme

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you work through snagging lists?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before we start.
What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for most snagging lists, longer for a run of plots. In Noel Park, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

Related advice
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. 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.
As a London address, Noel Park can be tricky for parking: let us know about parking bays, permits or a driveway. If you’ve bought a new home near Alexandra Palace station, the sealant around baths, showers and frames is worth checking in the first year or two.
