Hastingwood New Build Mastic
New-build sealant joints in Hastingwood need attention? We cut out the old, prepare the joints and apply the right sealant.
- Cracks appearing as a new home settles
- Cracked sealant around new window and door frames
- Beads laid onto grit and dust from the build
When something else is needed
In fairness, there are a few things sealant won’t fix:
- Plumbing faults behind the sealant
- Baths and trays that move too much for sealant to cope with
- Your warranty claim itself, which is between you and the builder
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before booking.

About our new build mastic in Hastingwood
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We work on show homes, plot handovers and windows & doors, and people most often call us about worktop and upstand sealant coming away and shower seals failing in the first year or two.
Older homes in small places like Hastingwood often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work comes with a 12-month guarantee, wherever you are in Essex.

Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

How we quote for new build mastic
We do not publish a price list, because jobs vary so much. What we look at:
- Mould in or behind the old joints
- The product the joint needs
- Whether the work is at height
- Any working-time requirements on site
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
What we need to know
To make quoting easier, please include:
- Where the job is, and your postcode
- How we’d reach the joints
- Whether it has been sealed before
- What’s wrong with the joints now
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or email us.
New build mastic in Hastingwood: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Around Hastingwood, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.
What you get with us
- We leave the area clean and tidy

How it works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. In a small place like Hastingwood, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Ventilate bathrooms well, especially in the first year
- Put sealant faults on your snagging list early
- Act quickly if a seal starts to leak
- Follow the cure time we give you
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
