New build mastic for homes and businesses in Ickleford
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. If you have leaking shower tray seals in a new home and internal frame sealant that has split, we can help, on bathrooms & en suites, skirting & floors and show homes alike.
Around Ickleford, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or email us.

What we cannot put right
To be straight with you, some problems need a different trade:
- Leaking fittings rather than failed sealant
- Cracking that points to a structural problem
- Movement caused by a poorly fitted tray or bath

Different surfaces, different methods
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out with baths filled first.
What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through cannot. Not sure whether yours can wait? You can call 0345 464 0079 or send us an email with a few photos and we will give you a straight answer. Around Ickleford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first.

Take a look at how sealant jobs are priced and customer reviews.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

How long before the joint can be used?

How do I get a quote for new build mastic in Ickleford?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.
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 doesn’t work out, we are happy to quote and our work is guaranteed for a year.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Report sealant problems to your builder during the snagging period
- Follow the cure time we give you
- Avoid running a DIY bead over the old one
- Act quickly if a seal starts to leak
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it, which can damage the surface.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
What happens on the day
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours in a single home. In a small place like Ickleford, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- Clear the area around the work
