What affects the cost of new build mastic
We quote each job individually. These are the things that affect it:
- Whether the work is at height
- Which sealant suits the joint
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
When you contact us, these details help:
- Whether it’s a home or a business
- How we’d reach the joints
- The problem you’ve noticed
- A few pictures by email, if you can
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
New build mastic for homes and businesses in Harlow
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. If you’re dealing with joints pulling apart as timber shrinks and sealant work across a run of new homes, we can help.
In a town like Harlow, skirting and floor joints open up as homes settle and floors move with the seasons. A flexible sealant, rather than rigid filler, keeps those joints closed.
Big or small, you get the same 12-month guarantee in Harlow and across Essex.

If you manage several properties in or around Harlow, jobs at different addresses can go on one quote. Send us the addresses and the work at each, and photos by email help.
Aftercare tips
To keep the joints looking good and working properly:
- Don’t wait for the house to settle if water is getting through
- Wait for the cure time before using a resealed shower
- Do not seal over failed sealant yourself
- Record problems with dated pictures
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
How the visit works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours in a single home. For a job in Harlow, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive

Advice
How the job changes by surface
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
Plot handovers
Send us the schedule and any sealant specification and we’ll quote. Sealant work across the plot is covered as agreed.
When it isn’t the sealant
New sealant cannot fix everything, and we’ll tell you before any work starts. Sealant will not put right:
- Structural cracks in walls or ceilings
- Baths and trays that move too much for sealant to cope with
- Plumbing faults behind the sealant
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

Common questions in Harlow
Can you help a landlord with a rental near Harlow Town station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is new build mastic in Harlow guaranteed?
All our work, in Harlow and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you come to Harlow?
We do. Our applicators work in Harlow, and the service is the same as everywhere else.
Should I wait before resealing?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How long does the job take?
Most jobs take a few hours for most snagging lists, longer for a run of plots. We will confirm how long when we quote.
Why deal with it now?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Black mould and gaps in sealant do not fix themselves, and in a busy home in Harlow they get worse with every use. Now is the easy time to put it right.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.

What new build mastic looks like in Harlow
Harlow is one of the post-war new towns. Newer neighbourhoods have been added to Harlow over the years. Newer homes need snagging; older ones need their joints renewing. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Harlow Town station, the sealant around baths, showers and frames is worth checking in the first year or two. In and around Harlow, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
