New-build mastic & snagging in Chaldon, Surrey
Our applicators work in Chaldon on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly.
- Worktop and upstand sealant coming away
- Plot mastic for developers ahead of handover
- Shower seals failing in the first year or two
How we handle new build mastic in Chaldon
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 are dealing with frame joints opening as the plaster dries and kitchen sealant that has pulled off the wall, we can put it right, on windows & doors, bathrooms & en suites and skirting & floors alike.
For a small place like Chaldon, the journey and access are planned in advance, and the work itself is the same as on any site.
A one-year guarantee comes as standard, so you are covered after we have gone.

What we are called out for in Chaldon
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Look out for these signs:
- Gaps behind new kitchen upstands
- Shower seals failing in the first year or two
- Smeared, uneven beads picked up at snagging
- Second-fix sealing on new plots
In and around Chaldon, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How we quote for new build mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Any working-time requirements on site
- Access and height
- The product the joint needs
- Whether there’s mould to deal with
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email.

- Photos by email, if that’s easy
- Access, such as stairs, a lift or height
For a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You will have a clear quote before work begins.
The process
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for most snagging lists, longer for a run of plots. In a small place like Chaldon, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints

Advice
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Settlement cracks that need a surveyor
- Deciding who is responsible under a builder’s warranty
- Damaged fittings that need replacing
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.

Is Chaldon in your area for new build mastic?

Where do you work from?
We are based in Crawley, and we cover South East England, London and all of Scotland.

What else we do in Chaldon
How the job changes by surface
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
