How we handle new build mastic in Northbridge Street
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a seal that’s letting water through needs doing now. We work on windows & doors, show homes and plot handovers, and common reasons people get in touch are skirting joints opening in the first winter and beads laid onto grit and dust from the build.
For a small place like Northbridge Street, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Big or small, you get the same 12-month guarantee.

What affects the quote in Northbridge Street
There’s no set price list, because jobs vary so much. What we look at:
- How many areas need sealing
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- Any working-time requirements on site
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
To make quoting easier, please include:
- Whether it has been sealed before
- The type of property
- Pictures of the joints, sent by email
- Where the job is, and your postcode
For a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. We’ll send you a clear quote before any work starts.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Use the extractor fan every time you shower
- Report sealant problems to your builder during the snagging period
- Wait for the cure time before using a resealed shower
- Don’t seal over failed sealant yourself
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Your questions about new build mastic in Northbridge Street
Do you work for landlords with property near Robertsbridge station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is Northbridge Street within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme. Tell us the plots and the joints involved for a clear quote.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

Signs you need new build mastic in Northbridge Street
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops.
The problems people usually mention when they call are:
- Internal frame sealant that has split
- New-build shower sealant that has already split
- Sealant that never bonded to the surface
- Smeared, uneven beads picked up at snagging
If you’ve bought a new home near Robertsbridge station, the sealant around baths, showers and frames is worth checking in the first year or two.

What we can’t put right
We’ll always be straight with you, so here’s what sealant can’t fix:
- Cracked trays, tiles or worktops
- Plumbing faults behind the sealant
- Baths and trays that move too much for sealant to cope with
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

Why act early in Northbridge Street
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In a small place like Northbridge Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear quote before any work starts.

What happens on the day
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Northbridge Street, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
Getting a quote
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand.
