Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in Baker Street and across Thurrock. Fully insured, ARBOMaster approved and guaranteed for a year.

How we handle new build mastic in Baker Street
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on show homes, kitchens and skirting & floors, and people most often call us about shower seals failing in the first year or two and cracks appearing as a new home settles.
For a small place like Baker Street, the journey and access are planned in advance, and the work itself is the same as on any site.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours in a single home. In a small place like Baker Street, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children

How to look after the new joints
After the cure time, these simple habits help:
- Look at the sealant regularly in the first couple of years
- Follow the cure time we give you
- Photograph failed sealant before it’s redone
- Wipe joints with warm soapy water
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you, so raise it early.
Baker Street questions
Do you work for landlords with property near Grays station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Is Baker Street within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Where is Mr Mastic based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months, large or small.
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’ll do.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
When to call us in Baker Street
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
It’s worth asking for a quote if you see:
- Leaking shower tray seals in a new home
- Sealant applied over dusty or wet surfaces
- Internal frame sealant that has split
- Joints pulling apart as timber shrinks
In and around Baker Street, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- How much experience the applicator has
- Whether they’re fully insured
- How the colour is chosen
- What happens if they find a problem under the old sealant

Skirting and floors
