New build mastic in Priddy's Hard
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly instead of bonding to the dust. Common call-outs are for kitchen sealant that has pulled off the wall and skirting joints opening in the first winter, across windows & doors, plot handovers and skirting & floors.
Around Priddy's Hard, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work comes with our one-year guarantee, wherever you are in Hampshire.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Clean sealant with mild detergent, not abrasives
- Wait for the cure time before using a resealed shower
- Report sealant problems to your builder during the snagging period
- Get a leaking seal dealt with right away
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it, which can damage the surface.
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 the new finishes intact.
Joints and finishes in Priddy's Hard homes
Priddy's Hard is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you’ve bought a new home near Portsmouth Harbour station, the sealant around baths, showers and frames is worth checking in the first year or two.

Surface by surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Plot handovers
Send us the schedule and any sealant specification for a quote. Sealant work across the plot is covered to the agreed spec.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The process
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours in a single home. Somewhere like Priddy's Hard needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height

Priddy's Hard questions
Do you cover Priddy's Hard for new build mastic?
Yes. Our work covers London and the South East, and Priddy's Hard is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Is Priddy's Hard within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
What does new build mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can new sealant go on top of the old bead?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. We cut the old bead out completely.
