Do you need new build mastic in Great Horwood?
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry first.
It’s worth asking for a quote if you see:
- Leaking shower tray seals in a new home
- Sealant applied over dusty or wet surfaces
- Worktop and upstand sealant coming away
- Cracked caulk along new skirting
For jobs in and around Great Horwood, choosing the right material for each joint is as important as a tidy finish.

New build mastic in Great Horwood, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We’re often asked to deal with cracked caulk along new skirting and internal frame sealant that has split, across kitchens, skirting & floors and bathrooms & en suites.
Older homes in small places like Great Horwood often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Resist patching a failed seal with a tube from the DIY shop
- Put sealant faults on your snagging list early
- Record problems with dated pictures
- Follow the cure time we give you
Don’t stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Questions from Great Horwood
Do you cover smaller places like Great Horwood?
Yes, Great Horwood is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What guarantee comes with new build mastic in Great Horwood?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
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.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
How long before the joint can be used?
It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in.

For landlords and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed.
Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Damaged fittings that need replacing
- Leaking fittings rather than failed sealant
- Movement caused by a poorly fitted tray or bath
