Our new build mastic service in Hampshire

Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We work on show homes, skirting & floors and windows & doors, and people most often call us about messy sealant that spoils new finishes and cracked sealant around new window and door frames.

The work is kept neat and contained to the area we are working on. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we explain the cure time before we leave.

First we work through your snagging list or plot schedule with you.
Failed or untidy sealant is cut out completely.
Surfaces are cleaned of building dust and primed where needed.
New sealant suited to each joint is applied and tooled neatly.
Finally, each room is checked and you’re given the cure time.

What you will pay

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

What you get with us

Arbo and Everbuild products
White, clear, grey or coloured to suit, where the product allows
Full insurance on every job
20+ years of sealant experience

New homes and floors across Hampshire

Our new build mastic work across Hampshire covers developers, householders and businesses, from Basingstoke, Winchester and Gosport to the quieter places in between. The common thread is movement: every joint has to allow for it.

Most of the South East has hard water, so limescale builds up on sealant, grout and fittings. Whatever the job in Hampshire, surfaces are cleaned back properly before new sealant goes in. In the coastal parts of Hampshire, the sea-facing side of a building takes the most weather, and that’s where sealant normally gives up first. The right product and careful preparation help it last.

Basingstoke: Around Basingstoke, as everywhere, new build mastic is only as good as the preparation behind it. For new homes near Basingstoke station, it’s worth checking the sealant early, while snags are still fresh.

How to look after the new joints

Simple care keeps the joints in good condition. Our advice:

Keep water off fresh sealant until it has cured
Resist patching a failed seal with a tube from the DIY shop
Report sealant problems to your builder during the snagging period
Get a leaking seal dealt with straight away

Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.

Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.

Quotes for new build mastic in Hampshire

We quote each job individually. These are the things that affect it:

Which sealant suits the joint
The number of rooms or windows
Whether there’s mould to deal with
How much old sealant there is and how hard it is to remove

How the job changes by surface

Plot handovers

Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed to keep callbacks down.

Skirting and floors

Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.

What we are called out for in Hampshire

New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open and the sealant has to cope with the movement.

Look out for any of the following:

Cracks appearing as a new home settles
Smeared, uneven beads picked up at snagging
Sealant that never bonded to the surface
Skirting joints opening in the first winter

Should I try it myself first?

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
