About our new build mastic in Great Parndon
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. Common call-outs are for gaps opening as the house dries out and settles and messy sealant that spoils new finishes, across show homes, bathrooms & en suites and skirting & floors.
In and around Great Parndon, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
You get a 12-month guarantee, the same in Great Parndon as everywhere else we work.

Leave it or put it right?
A hairline gap at a skirting can wait, but a leaking seal cannot. Not sure whether yours can wait? You can ring 0345 464 0079 or email us with a few pictures and we’ll tell you. Around Great Parndon, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

What the job involves on each surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
Questions from Great Parndon
I let a flat near Harlow Town station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Do you cover smaller places like Great Parndon?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do plot mastic on a new development?
Yes. We work through plots to your schedule ready for handover. Tell us the plots and the joints involved for a clear quote.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do you work through snagging lists?
Yes. Send us the sealant items on the list, with photos if you can and we’ll give you a quote. We will tell you if anything on it is not a sealant job.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.
When to call us in Great Parndon
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Most people get in touch when they notice one of these:
- Skirting joints opening in the first winter
- Sealant that never bonded to the surface
- Sealant work across a run of new homes
- Leaking shower tray seals in a new home
In and around Great Parndon, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.

Great Parndon is part of Harlow, one of the post-war new towns. Harlow has kept growing, with newer neighbourhoods added to the original town.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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.
When it isn’t the sealant
We won’t take on work that will not last, so these are the limits:
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
- Leaks from pipes, valves or wastes, which need a plumber
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
