Sandway New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in Sandway and across Kent. Fully insured, ARBOMaster approved and guaranteed for a year.
- Gaps behind new kitchen upstands
- Untidy sealant flagged on a snagging list
- Frame joints opening as the plaster dries
What the job involves on each surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in and baths are filled before sealing.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and prime where the product needs it.
About our new build mastic in Sandway
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks rather than sitting on a layer of grit. We’re often asked to deal with joints pulling apart as timber shrinks and gaps between new skirting and floors, on show homes, windows & doors and plot handovers.
Somewhere as small as Sandway, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What affects the quote in Sandway
We quote each job individually. This is what makes a difference:
- Mould in or behind the old joints
- The number of rooms or windows
- Whether the work is at height
- The old material and how stubborn it is
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- The type of property
- Access, such as stairs, a lift or height
- A few pictures by email, if you can
- The address or postcode of the job
For a quote, ring 0345 464 0079 or email us and tell us where the job is and what the problem looks like. We will give you a clear price before any work starts.
Landlord and commercial work in Sandway
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Housing providers, facilities teams and property managers book us too in Sandway and across Kent. We can quote a run of properties together, and we’re fully insured.
Looking after it afterwards
So the new joints stay in good condition:
- Keep pictures and emails about snagging items
- Use the extractor fan every time you shower
- Avoid running a DIY bead over the old one
- Report sealant problems to your builder during the snagging period
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.
When to call us in Sandway
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Any of these means the joints need attention:
- Frame joints opening as the plaster dries
- Shower seals failing in the first year or two
- Sealant work across a run of new homes
- Cracks appearing as a new home settles
If you’ve bought a new home near Lenham station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before booking anyone
- Who does the work, and how experienced they are
- What guarantee comes with the work
- When the joint can take water or movement
- Which colour the sealant will be
What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes anything from a few hours to several days, depending on the number of plots. In a small place like Sandway, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property

Sandway: your questions answered
Will you come out to Sandway?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Lenham station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.
Should I go to my builder first?
Report it to the builder first while you’re covered. If it is not resolved, we can reseal it properly.
Do you guarantee your work?
Yes. Every job comes with our one-year guarantee.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
