New Build Mastic in Chelmsford
We cover Chelmsford for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly.
- Sealant that never bonded to the surface
- Smeared, uneven beads picked up at snagging
- Gaps between new skirting and floors
How we handle new build mastic in Chelmsford
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. Common call-outs are for frame joints opening as the plaster dries and sealant applied over dusty or wet surfaces, across kitchens, show homes and plot handovers.
A place the size of Chelmsford has new developments as well as older streets. New homes need their plot mastic and sealant finished well, and owners often find snags in the first year or two, as a new house dries out and settles.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.
Landlord and commercial work in Chelmsford
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Why act early in Chelmsford
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. In flats, shops and offices in Chelmsford, a failed joint can let water into the unit below or behind a wall, where it’s often found late and is bigger to put right.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It usually takes anything from a few hours to several days, depending on the number of plots. For homes and businesses in busier parts of Chelmsford, parking needs a little planning. For flats, mention stairs, lifts and shared entrances as well.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

Advice
What affects the cost of new build mastic
Every job gets its own quote. These are the things that affect it:
- Whether there’s mould to deal with
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
What we need to know
Before you ask for a quote, have a think about:
- Photos by email, if that is easy
- Access, such as stairs, a lift or height
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved and give you a clear price.
What we can’t put right
We will not take on work that will not last, so here’s what sealant cannot put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
- Movement caused by a poorly fitted tray or bath
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before booking.

Common questions in Chelmsford
Is Chelmsford in your area for new build mastic?
Yes. Our work covers London and the South East, and Chelmsford is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
What guarantee comes with new build mastic in Chelmsford?
All our work, in Chelmsford and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Can you work from my snagging list?
Yes. Send us the sealant items on the list, with pictures if you can, and we will quote. We’ll tell you if anything on it isn’t a sealant job.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Should I go to my builder first?
If you’re still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Do you work for landlords and businesses?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Essex.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Act quickly if a seal starts to leak
- Watch for new gaps as the house dries out
- Do not seal over failed sealant yourself
- Report sealant problems to your builder during the snagging period
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
