About our new build mastic in Waterford
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on bathrooms & en suites, plot handovers and kitchens, and the jobs we see most are skirting joints opening in the first winter and kitchen sealant that has pulled off the wall.
For a small place like Waterford, the journey and access are planned in advance, and the work itself is the same as on any site.
A 12-month guarantee comes as standard.

What the job involves on each surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing.
What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Around Waterford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit normally makes better use of the time than several visits. We will give you a clear price for the lot.
Why book with us
- A 12-month guarantee on all work
- We agree the colour with you first
- A sealant colour to suit the surroundings
- We never seal over old sealant
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
What affects the cost of new build mastic
The price is agreed before any work begins. It takes into account:
- Any working-time requirements on site
- Whether there’s mould to deal with
- Access and height
- Which sealant suits the joint
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.
Asking for a quote
What to tell us when you ask for a quote:
- The problem you’ve noticed
- Whether it has been sealed before
- Where the job is, and your postcode
- Whether it’s a home or a business
We quote each job on its own, so start by telling us what you need. Simply ring 0345 464 0079 or email us and describe the job and send pictures if you have them.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the number of plots and we leave things clean and tidy. For a village or hamlet like Waterford, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
- Move anything stored near the joints
Ask for a quote
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.

Waterford questions
Will you come out to Waterford?
Yes, Waterford is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Hertford North station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do you use white or clear sealant?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
Can you reseal over the builder’s sealant?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. We cut the old bead out completely.
How do I get a quote for new build mastic in Waterford?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
When to call us in Waterford
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
The most common problems we see are:
- Gaps between new skirting and floors
- Cracks appearing as a new home settles
- Second-fix sealing on new plots
- Kitchen sealant that has pulled off the wall
In and around Waterford, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- Which sealant they’ll use, and why
- How long to leave it before use
- How hidden problems are handled
- Whether they seal over old material or remove it

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep pictures and emails about snagging items
- Act quickly if a seal starts to leak
- Wait for the cure time before using a resealed shower
- Report sealant problems to your builder during the snagging period
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and protects the rest of the house.
