New build mastic in Elmdon, done properly
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. Typical jobs include untidy sealant flagged on a snagging list and frame joints opening as the plaster dries, across kitchens, show homes and skirting & floors.
Work in a small place like Elmdon just needs the journey and access planning, and the work itself is the same as on any site.
All our work is covered by a one-year guarantee.

Aftercare tips
After the cure time, these simple habits help:
- Clean sealant with mild detergent, not abrasives
- Act quickly if a seal starts to leak
- Watch for new gaps as the house dries out
- Keep water off fresh sealant until it has cured
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
Do you need new build mastic in Elmdon?
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Look out for these signs:
- Shower seals failing in the first year or two
- Kitchen sealant that has pulled off the wall
- Messy sealant that spoils new finishes
- Cracked caulk along new skirting
Around Elmdon, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote
- How the surfaces are prepared before sealing
- Whether you can choose the colour
- What the cure time is
- Is the old sealant removed completely?
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home. For a village or hamlet like Elmdon, 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.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit

Joints and finishes in Elmdon homes

What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Older cottages and farmhouses around Elmdon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What the job involves on each surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed to keep callbacks down.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one in a matching colour.
FAQs for Elmdon
Can you help a landlord with a rental near Great Chesterford station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Is Elmdon within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
My new home is still under warranty. Should I contact you?
Your builder, if you are still in their snagging or warranty period. If that does not work out, we’re happy to quote with our 12-month guarantee.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Do you take on second-fix sealing for builders?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
