When it isn’t the sealant

- Baths and trays that move too much for sealant to cope with
- Damaged fittings that need replacing
- Your warranty claim itself, which is between you and the builder

How we handle new build mastic in Sarsden
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference, because that is what rushed new-build sealant usually lacks. If you have skirting joints opening in the first winter and second-fix sealing on new plots, we can put it right, on bathrooms & en suites, skirting & floors and plot handovers alike.
Work in a small place like Sarsden just needs the journey and access planning, and the work itself is the same as on any site.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

When to call us in Sarsden
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
Most people get in touch after spotting one of these:
- Gaps opening as the house dries out and settles
- Gaps between new skirting and floors
- Messy sealant that spoils new finishes
- Beads laid onto grit and dust from the build
For new homes near Kingham station, it’s worth checking the sealant early, while snags are still fresh.

Your questions about new build mastic in Sarsden
Do you cover Sarsden for new build mastic?
Yes, Sarsden is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.
Do you work for landlords with property near Kingham station?
Yes. We work for letting agents and landlords as well as householders. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can you match the sealant colour to my new kitchen or bathroom?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.
Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.
Is there any odour?
There can be a smell while the sealant cures. Opening a window helps.
How long will you be here?
That depends on the amount of work, but most jobs take a few hours in a single home. We will tell you when we quote.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What happens if it’s left?
The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a small place like Sarsden, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
Why us?
- ARBOMaster approved applicator
- Anti-fungal silicone where joints get wet
- We never seal over old sealant
- 20+ years of sealant experience
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Report sealant problems to your builder during the snagging period
- Wipe joints with warm soapy water
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
What we do, step by step
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots for a typical job. In a small place like Sarsden, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

There’s no standard price list, because every job is different. Instead, we give you a clear price for your job. To arrange one, phone 0345 464 0079 or email us.
