Your questions about new build mastic in Paulsgrove
Is Paulsgrove in your area for new build mastic?
Yes, Paulsgrove is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will send you a clear quote.
Do you work for landlords with property near Cosham station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
New build mastic in Paulsgrove
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you’re dealing with joints pulling apart as timber shrinks and smeared, uneven beads picked up at snagging, we can put it right, whatever the surface.
For a new home in or near Paulsgrove, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
Big or small, it’s backed by our one-year guarantee in Paulsgrove and across Portsmouth.

How the visit works
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours in a single home. Parking around Paulsgrove is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height

New build mastic in Paulsgrove: local notes
Paulsgrove is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Paulsgrove, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Paulsgrove is about 3 miles north of Portsmouth, in Portsmouth. Wherever you are in the PO6 postcode area, we can carry out new build mastic at your property. Paulsgrove is one of 19 towns and villages in Portsmouth we cover.
All of PO6 is covered for new build mastic. Whether your property is on Bourne Road, Ludlow Road and Farmlea Road or anywhere close by, we can help. Being close to the M27 and A27, Paulsgrove is easy for our applicators to reach for new build mastic. If you’re just outside Paulsgrove, we cover Wymering (1 mile east), Cosham (1 mile east), Hilsea (2 miles south-east), Widley (2 miles east) and Purbrook Heath (2 miles north-east). We also work in nearby towns such as Portsmouth (3 miles south), Southsea (5 miles south), Milton (4 miles south), Landport (3 miles south), Baffins (3 miles south-east) and Portsea (4 miles south).

Locally, jobs take us to homes and businesses close to Alexandra Park, The Sir Alec Rose pub and Castle View Academy and the streets around them. The nearest railway station is Cosham station, about 1.2 miles south-east.

What the job involves on each surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing to keep callbacks down.
When to call us in Paulsgrove
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
The most common problems we see are:
- Second-fix sealing on new plots
- Gaps between new skirting and floors
- Frame joints opening as the plaster dries
- Untidy sealant flagged on a snagging list
For new homes near Cosham station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- Whether the sealant suits the joint
- Whether they seal over old material or remove it
- What happens if the job turns out different
- The length of the guarantee
Why it’s worth doing now in Paulsgrove
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times to plan around. In a smaller place like Paulsgrove, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
Why book with us
- Colour picked to suit the job
- Old sealant always removed completely
- ARBOMaster approved applicator

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Raise failed sealant with the developer while you’re covered
- Follow the cure time we give you
- Resist patching a failed seal with a tube from the DIY shop
- Wipe joints with warm soapy water
Don’t stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
