New build mastic in Tipner
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 failed shower or bath seal shouldn’t wait. If you’re dealing with shower seals failing in the first year or two and cracks appearing as a new home settles, we can put it right, whatever the surface.
In and around Tipner, floors range from older timber boards to tiles and newer finishes, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Why act early in Tipner
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times to plan around. In an older home around Tipner, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
Why book with us
- Every job guaranteed for a year
- Anti-fungal silicone where joints get wet

Questions from Tipner
Can you help a landlord with a rental near Portsmouth & Southsea station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Will you come out to Tipner?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
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.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you use white or clear sealant?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
Why does sealant fail so quickly in new builds?
It’s common, and there are normally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We will give you a better idea when we quote.
Honest limits
Sealant is not the answer to every problem, and we’ll tell you before work begins. Sealant won’t put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Broken tiles or a split tray
- Cracking that points to a structural problem
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Keep pictures and emails about snagging items
- Avoid scourers and strong chemicals on sealant
- Follow the cure time we give you
- Look at the sealant regularly in the first couple of years
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for most snagging lists, longer for a run of plots. Parking around Tipner 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.
- Old sealant is cut out and the joints cleaned.
- 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.
- We check every joint and leave you with the cure times.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
How to get a quote
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we will come back to you with a quote.
