Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or send us an email.
How much does new build mastic cost in Swallowfield?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before any work starts.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Why act early in Swallowfield
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Where a wall is exposed, as many are in small places like Swallowfield, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

Advice
Do you need new build mastic in Swallowfield?
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
People normally contact us after spotting one of these:
- Smeared, uneven beads picked up at snagging
- Gaps between new skirting and floors
- Frame joints opening as the plaster dries
- Sealant work across a run of new homes
For new homes near Mortimer station, it’s worth checking the sealant early, while snags are still fresh.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Resist patching a failed seal with a tube from the DIY shop
- Keep photos and emails about snagging items
- Clean sealant with mild detergent, not abrasives
- Put sealant faults on your snagging list early
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day before water reaches them.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
