About our new build mastic in Hangleton
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation, because that is what rushed new-build sealant usually lacks. If you’re dealing with sealant applied over dusty or wet surfaces and gaps between new skirting and floors, we can put it right, on kitchens, windows & doors and skirting & floors alike.
In and around Hangleton, floors range from older timber boards to tiles and newer finishes, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
Big or small, it’s backed by our one-year guarantee.

How the job changes by surface
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and prime where the product needs it.
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Why deal with it now?
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. In an older home around Hangleton, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What else we do in Hangleton
What affects the cost of new build mastic
Jobs vary more than people expect. What affects the quote:
- Working hours on commercial sites
- The number and length of the joints
- The type of sealant required
- How easy the joints are to reach
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What we need to know
Photos by email are helpful but not essential. Please mention:

- Any access issues, like height or stairs
- The rough size of the job
- Where the property is

FAQs for Hangleton
Is Hangleton within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Portslade station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Should I wait before resealing?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We will go through the sealant items and agree what we will do.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
The process
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. Parking around Hangleton is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
Getting ready for the visit
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules
- Move anything stored near the joints
Ask for a quote
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
Advice
When something else is needed
A few problems are outside what sealant work can do:
- Your warranty claim itself, which is between you and the builder
- Plumbing faults behind the sealant
- Structural cracks in walls or ceilings
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Kitchens
- Bathrooms & en suites
- Plot handovers
- Skirting & floors
- Show homes
- Windows & doors
Can I do it myself?
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, and the work is guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Common problems we fix in Hangleton
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.
Common reasons people contact us include:
- Gaps behind new kitchen upstands
- Skirting joints opening in the first winter
- Sealant work across a run of new homes
- Sealant applied over dusty or wet surfaces
If you’ve bought a new home near Portslade station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- How long the guarantee is
- Whether the sealant suits the joint
- When the joint can take water or movement
- How the surfaces are prepared before sealing
