What we need to know
You don’t need to know the technical terms. Just tell us:
- Where the property is

Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work.
New build mastic in Shorwell, done properly
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. If you’re dealing with cracked caulk along new skirting and plot mastic for developers ahead of handover, we can help, on plot handovers, show homes and windows & doors alike.
In a village or hamlet like Shorwell, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All of our work is guaranteed for twelve months, in Shorwell and everywhere else we cover.

Honest limits
New sealant cannot fix everything, and we will tell you before any work starts. It won’t solve:
- Plumbing faults behind the sealant
- Baths and trays that move too much for sealant to cope with
- Structural cracks in walls or ceilings

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Follow the cure time we give you
- Resist patching a failed seal with a tube from the DIY shop
- Open a window or run the fan after bathing
- Put sealant faults on your snagging list early
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
What we’re called out for in Shorwell
Sealant applied onto damp surfaces does not bond well. On a busy site, joints aren’t always given time to dry first.
Common reasons people contact us include:
- Cracks appearing as a new home settles
- Messy sealant that spoils new finishes
- Gaps behind new kitchen upstands
- Frame joints opening as the plaster dries
In and around Shorwell, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What we do, step by step
We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job usually takes anything from a few hours to several days, depending on the number of plots. In a small place like Shorwell, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

What new build mastic looks like in Shorwell
Shorwell is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For jobs in and around Shorwell, choosing the right material for each joint is as important as a tidy finish.

Surface by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk.
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
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, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

When is the best time to reseal in a new build?
That depends on the joint. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
Do you use white or clear sealant?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before work begins.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we are using and why.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
