How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Avoid scourers and strong chemicals on sealant
- Raise failed sealant with the developer while you’re covered
- Keep water off fresh sealant until it has cured
- Don’t wait for the house to settle if water is getting through
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture doesn’t sit on the sealant.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
New build mastic in Sandford
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first, and if it isn’t put right, get in touch with us. Common call-outs are for leaking shower tray seals in a new home and cracked caulk along new skirting, across kitchens, windows & doors and bathrooms & en suites.
Work in a small place like Sandford just needs the journey and access planning, and the work itself is the same as on any site.

How the job changes by surface
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Your questions about new build mastic in Sandford
Will you come out to Sandford?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do new build mastic in Sandford?
Yes, Sandford is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear price.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
Is it normal for sealant to crack in a new home?
There are generally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
What colour sealant will you use?
Most bathroom joints are white or clear, but sealant comes in other colours too. We choose one to suit the room and agree it with you.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
When something else is needed
To be straight with you, some problems need a different trade:
- Your warranty claim itself, which is between you and the builder
- Structural cracks in walls or ceilings
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

When to call us in Sandford
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
If you can see any of these, it’s time to have the joints looked at:
- Sealant work across a run of new homes
- Messy sealant that spoils new finishes
- Worktop and upstand sealant coming away
- Internal frame sealant that has split
Around Sandford, as everywhere, new build mastic is only as good as the preparation behind it.

Why act early in Sandford
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. In a small place like Sandford, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.
Why Sandford customers choose us
- A 12-month guarantee on all work
