New-build mastic & snagging in Baybridge, Hampshire
We cover Baybridge for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Worktop and upstand sealant coming away
- Gaps between new skirting and floors
- Beads laid onto grit and dust from the build
New build mastic in Baybridge, done properly
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. Typical jobs include sealant applied over dusty or wet surfaces and sealant work across a run of new homes, across skirting & floors, show homes and kitchens.
In a village or hamlet like Baybridge, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Surface by surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
What happens on the day
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for most snagging lists, longer for a run of plots in most cases. In a small place like Baybridge, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property

Advice
Why deal with it now?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Around Baybridge, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.

Common problems we fix in Baybridge
Sealant applied onto damp surfaces does not bond well. Site programmes don’t always leave time for joints to dry.
Keep an eye out for any of the following:
- Second-fix sealing on new plots
- Cracked sealant around new window and door frames
- Cracked caulk along new skirting
- Leaking shower tray seals in a new home
If you’ve bought a new home near Shawford station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before you book anyone
- The length of the guarantee
- Which colour the sealant will be
- Whether VAT is included
- Which sealant they’ll use, and why
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Watch for new gaps as the house dries out
- Resist patching a failed seal with a tube from the DIY shop
- Follow the cure time we give you
- Do not wait for the house to settle if water is getting through
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you, so raise it early.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
DIY sealant or a professional job?
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 does not work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
