How we handle new build mastic in Merrow
We work in new homes and on new-build sites across Merrow. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on skirting & floors, windows & doors and kitchens, and common reasons people get in touch are internal frame sealant that has split and gaps opening as the house dries out and settles.
In and around Merrow, floors range from older timber boards to tiles and newer finishes, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
Every job comes with our one-year guarantee, wherever you are in Surrey.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid scourers and strong chemicals on sealant
- Check bath and shower seals every few months as the house settles
- Use the extractor fan every time you shower
- Put sealant faults on your snagging list early
Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
Quotes for new build mastic in Merrow
For a quick quote, just ask. What matters most is:
- How many areas need sealing
- The old material and how stubborn it is
- Any working-time requirements on site
- The size of the job
The cost reflects the work involved, not guesswork. That is why we ask about the job first.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- The type of property
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Merrow questions
Can you do new build mastic in Merrow?
Yes, Merrow is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Do you work for landlords with property near Clandon station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
How long does the job take?
A typical job takes a few hours in a single home. We will confirm how long when we quote.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.

Leave it or put it right?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. In a smaller place like Merrow, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

How the visit works
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours in a single home. A visit to Merrow is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- 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.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
- Clear the area around the work

Advice
Do you need new build mastic in Merrow?
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.
Signs it’s time to call us include:
- Skirting joints opening in the first winter
- Messy sealant that spoils new finishes
- Gaps opening as the house dries out and settles
- Worktop and upstand sealant coming away
For new homes near Clandon station, it’s worth checking the sealant early, while snags are still fresh.
