New build mastic in South Holmwood, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We work on plot handovers, kitchens and windows & doors, and common reasons people get in touch are beads laid onto grit and dust from the build and gaps opening as the house dries out and settles.
Around South Holmwood, 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.
We stand behind the work with a one-year guarantee.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Use the extractor fan every time you shower
- Clean sealant with mild detergent, not abrasives
- Check bath and shower seals every few months as the house settles
- Follow the cure time we give you
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
Work for landlords, hotels and businesses
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Common problems we fix in South Holmwood
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Look out for any of the following:
- Shower seals failing in the first year or two
- Cracks appearing as a new home settles
- Smeared, uneven beads picked up at snagging
- Skirting joints opening in the first winter
If you’ve bought a new home near Holmwood station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- How much experience the applicator has
- What happens if the job turns out different
- Whether VAT is included
- What product goes in the joint
What happens if it’s left?
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. Not sure whether yours can wait? You can phone 0345 464 0079 or email us with a few pictures and we’ll give you a straight answer. Older cottages and farmhouses around South Holmwood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

What the job involves on each surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.

How it works
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job.

- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work

Advice
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
