How it works
When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work normally takes anything from a few hours to several days, depending on the number of plots. In Fareham, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises

How we handle new build mastic in Fareham
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. We work on skirting & floors, plot handovers and show homes, and people most often call us about sealant work across a run of new homes and gaps between new skirting and floors.
In a town like Fareham, skirting and floor joints open up as homes settle and floors move with the seasons. A flexible sealant, rather than rigid filler, keeps those joints closed.
Big or small, it’s backed by our one-year guarantee.
When something else is needed
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Broken tiles or a split tray
- Your warranty claim itself, which is between you and the builder
- Leaks from pipes, valves or wastes, which need a plumber
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.

New build mastic around Fareham
Fareham is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Fareham station, the sealant around baths, showers and frames is worth checking in the first year or two.

Your questions about new build mastic in Fareham
Do you work for landlords with property near Fareham station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Is there a guarantee on new build mastic in Fareham?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
When is the sealant fully cured?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.

What affects the cost of new build mastic
We do not publish a price list, because jobs vary so much. What we look at:
- Whether there’s mould to deal with
- The size of the job
- Whether old sealant or filler has to be cut out
- Access and height
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- Roughly how big the job is
- How we’d reach the joints
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved and give you a clear price.
Do you need new build mastic in Fareham?
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Look out for these signs:
- Gaps behind new kitchen upstands
- Joints pulling apart as timber shrinks
- Sealant work across a run of new homes
- Internal frame sealant that has split
Around Fareham, as everywhere, new build mastic is only as good as the preparation behind it.

Why it’s worth doing now in Fareham

Gaps in sealant and mould in the bead never get better on their own, and in a busy household in Fareham they spread with every shower and every downpour. Replacing the sealant now is the simplest fix.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Any old sealant cut out fully, not covered over
- White, clear, grey or another colour, product permitting
- 12-month guarantee on every job
- Over 20 years’ experience

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
- Check bath and shower seals every few months as the house settles
- Report sealant problems to your builder during the snagging period
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and protects the rest of the house.
