How we handle new build mastic in The Haven
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you’re dealing with cracked sealant around new window and door frames and skirting joints opening in the first winter, we can put it right, on skirting & floors, show homes and kitchens alike.
Around The Haven, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
We stand behind the work with a 12-month guarantee.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

What affects the cost of new build mastic
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- Working hours on commercial sites
- How many areas need sealing
- How easy the joints are to reach
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.
Helping us quote
There’s no need for technical detail. Just tell us:
- Roughly how big the job is
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
There’s no standard price list, because every job is different. Instead, we give you a clear quote for your job. To arrange one, phone 0345 464 0079 or drop us an email.
How it works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours in a single home. In a small place like The Haven, 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 any work starts.
- We remove the failed sealant and clean the joints.
- 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.
- We check every joint and leave you with the cure times.

Advice
FAQs for The Haven
Do you work for landlords with property near Billingshurst station?
Yes, we work for letting agents and landlords. You can call 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.
Do you cover smaller places like The Haven?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
How do I get a quote for new build mastic in The Haven?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
How long does new build mastic take?
Most jobs take anything from a few hours to several days, depending on the number of plots. Your quote will say how long we expect yours to take.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. If something is not sealant, we will say so.
How the job changes by surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Leave it or put it right?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. In a small place like The Haven, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

What sealant work can’t fix
In fairness, there are a few things sealant won’t fix:
- Your warranty claim itself, which is between you and the builder
- Structural cracks in walls or ceilings
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.

How to look after the new joints
To keep the joints looking good and working properly:
- Record problems with dated photos
- Report sealant problems to your builder during the snagging period
- Use the extractor fan every time you shower
- Wait for the cure time before using a resealed shower
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents, 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.
