New build mastic in Orsett Heath, done properly
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that is letting water through needs doing now. We work on windows & doors, bathrooms & en suites and kitchens, and common reasons people get in touch are second-fix sealing on new plots and gaps opening as the house dries out and settles.
Somewhere as small as Orsett Heath, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
All our work is covered by a 12-month guarantee.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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.
New build mastic in Orsett Heath: local notes
Orsett Heath is within about 3 miles of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Grays station, it’s worth checking the sealant early, while snags are still fresh. In and around Orsett Heath, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Orsett Heath is about 1 mile north-east of Grays, in Thurrock.

Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
How long does new build mastic take?
Most jobs take a few hours for most snagging lists, longer for a run of plots. We’ll confirm how long when we quote.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Thurrock.
Is it worth resealing while the house is still settling?
Any seal that’s leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
The process
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the amount of work. In a small place like Orsett Heath, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

What else we do in Orsett Heath
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Watch for new gaps as the house dries out
- Keep water off fresh sealant until it has cured
- Act quickly if a seal starts to leak
- Wipe joints with warm soapy water
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Leaking fittings rather than failed sealant
- Cracked trays, tiles or worktops
- Cracking that points to a structural problem
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.
What we seal
- Plot handovers
- Bathrooms & en suites

How we quote for new build mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number and length of the joints
- The old material and how stubborn it is
- Any working-time requirements on site
- Whether there’s mould to deal with
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
Asking for a quote
When you contact us, it’s useful to know:
- Where the property is
- A few pictures by email, if you can
- If someone has resealed it before
- The rough size of the job
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved.
How the job changes by surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Why act early in Orsett Heath
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Where a wall is exposed, as many are in small places like Orsett Heath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
Why us?
- Fully insured
- A choice of colours where the product allows
- One-year guarantee on every job
- Any old sealant cut out fully, not covered over
