New build mastic in Broad Green, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. Common call-outs are for second-fix sealing on new plots and gaps between new skirting and floors, across show homes, bathrooms & en suites and kitchens.
Older homes in small places like Broad Green often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
All our work comes with a 12-month guarantee, wherever you are in Essex.

New build mastic around Broad Green
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Marks Tey station, it’s worth checking the sealant early, while snags are still fresh.

Questions from Broad Green
Will you come out to Broad Green?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Marks Tey station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Are you insured?
Yes. Full insurance covers our work.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme, room by room. Get in touch with the number of plots and the scope and we’ll quote.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
What happens if it’s left?
The builder is generally the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. Where a wall is exposed, as many are in small places like Broad Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
Why choose Mr Mastic in Broad Green
- Tidy, careful work
- We are fully insured
- Every job guaranteed for a year
- Experience in homes, commercial sites and hotels
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Common problems we fix in Broad Green
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
If you can see any of these, it’s time to have the joints looked at:
- Gaps behind new kitchen upstands
- Joints pulling apart as timber shrinks
- Sealant work across a run of new homes
- Beads laid onto grit and dust from the build
Around Broad Green, as everywhere, new build mastic is only as good as the preparation behind it.

What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Broad Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep photos and emails about snagging items
- Wipe joints with warm soapy water
- Don’t seal over failed sealant yourself
- Wait for the cure time before using a resealed shower
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
For landlords and businesses
We work for landlords and agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
