- Untidy sealant flagged on a snagging list
- Worktop and upstand sealant coming away
New build mastic in Watersfield
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you are dealing with worktop and upstand sealant coming away and gaps between new skirting and floors, we can put it right, on bathrooms & en suites, skirting & floors and kitchens alike.
Around Watersfield, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Your job is guaranteed for a year, as with all our work.

New build mastic in Watersfield: local notes

In and around Watersfield, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Pulborough station, the sealant around baths, showers and frames is worth checking in the first year or two.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Ventilate bathrooms well, especially in the first year
- Follow the cure time we give you
- Put sealant faults on your snagging list early
- Resist patching a failed seal with a tube from the DIY shop
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
The process
Most of a good job is in the preparation, and we do not rush it. 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. For a village or hamlet like Watersfield, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What the job involves on each surface
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed.
Quotes for new build mastic in Watersfield
The price is agreed before any work begins. It takes into account:
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- How many areas need sealing
- Working hours on commercial sites
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before we start.
What we need to know
To make quoting easier, let us know:
- If someone has resealed it before
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work and send you a clear quote.
Why deal with it now?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Around Watersfield, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

What we can’t put right

- Leaking fittings rather than failed sealant
- Cracked trays, tiles or worktops
- Deciding who is responsible under a builder’s warranty

Your questions about new build mastic in Watersfield
Can you help a landlord with a rental near Pulborough station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Watersfield?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
Can you do several jobs on one visit?
Yes. Just list everything you need.
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, but cosmetic gaps can wait for movement to slow.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours for most snagging lists, longer for a run of plots. We’ll tell you when we quote.
