New-build mastic & snagging in Hanover, Brighton and Hove
Problem with your new-build sealant joints in Hanover? We cut out the old, prepare the joints and apply the right sealant.
- Shower seals failing in the first year or two
- Sealant that never bonded to the surface
- Kitchen sealant that has pulled off the wall
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours in a single home. In a smaller place like Hanover, parking is seldom the issue; lanes, gates and long drives are worth mentioning. 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.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in

Advice
About our new build mastic in Hanover
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. We work on show homes, skirting & floors and bathrooms & en suites, and people most often call us about internal frame sealant that has split and second-fix sealing on new plots.
In smaller places like Hanover, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Common questions in Hanover
Will you come out to Hanover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Hanover for new build mastic?
Yes. Our work covers London and the South East, and Hanover is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What affects the cost of new build mastic
Jobs vary more than people expect. What affects the quote:
- Working hours on commercial sites
- Whether the work is at height
- The type of sealant required
- Mould in or behind the old joints
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
What we need to know
What to tell us when you ask for a quote:
- Access, such as stairs, a lift or height
- The type of property
- Where the job is, and your postcode
- If someone has resealed it before
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
Different surfaces, different methods
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed so the sealant lasts.
What we’re called out for in Hanover
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Signs it’s time to call us include:
- Cracked caulk along new skirting
- Plot mastic for developers ahead of handover
- Worktop and upstand sealant coming away
- Internal frame sealant that has split
In and around Hanover, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- How long the guarantee is
- How the colour is chosen
- What product goes in the joint
- Whether they’re fully insured
Landlords, agents and businesses in Hanover
We also work for property managers and facilities teams in Hanover and across Brighton and Hove. We can quote a run of properties together, and we are fully insured.
If you manage several properties in or around Hanover, several properties can go on one quote. Send us the addresses and the work at each.
What sealant work cannot fix
We will always be straight with you, so here’s what sealant cannot fix:
- Baths and trays that move too much for sealant to cope with
- Settlement cracks that need a surveyor
- Deciding who is responsible under a builder’s warranty
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.
Joints and surfaces we work on
- Bathrooms & en suites
- Kitchens
- Windows & doors
- Plot handovers
- Skirting & floors
- Show homes
Why act early in Hanover
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a smaller place like Hanover, 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.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What you get with us
- Homes, businesses and hotels
- More than 20 years in sealant work
- One-year guarantee on every job

New build mastic in Hanover: local notes
Hanover is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, 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.
If you’ve bought a new home near Brighton station, the sealant around baths, showers and frames is worth checking in the first year or two.
