Questions from Calvert
Can you do new build mastic in Calvert?
Yes, Calvert is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Calvert?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work through snagging lists?
Yes. Send it with pictures and we will quote for the sealant items. If something is not sealant, we’ll say so.
How do I get a quote for new build mastic in Calvert?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or email us and let us know what needs doing and where.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
How we handle new build mastic in Calvert
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. If you have new-build shower sealant that has already split and messy sealant that spoils new finishes, we can help, whatever the surface.
Work in a small place like Calvert just needs the journey and access planning, and once on site, the job is the same as anywhere.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Signs you need new build mastic in Calvert
Sealant applied onto damp surfaces doesn’t bond well. Site programmes do not always leave time for joints to dry first.
The problems people usually mention when they call are:
- Leaking shower tray seals in a new home
- Cracked sealant around new window and door frames
- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
For jobs in and around Calvert, choosing the right material for each joint is as important as a tidy finish.
What your quote should include
- The length of the guarantee

- Whether VAT is included
- How the joint is cleaned and prepared
Leave it or put it right?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Older cottages and farmhouses around Calvert can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

What else we do in Calvert
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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.
What affects the quote in Calvert
You’ll get a clear quote before any work starts. It’s based on:
- The number of rooms or windows
- Whether the work is at height
- The old material and how stubborn it is
- The product the joint needs
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.
What to tell us for a quote
When you call or email, these details help:
- The rough size of the job
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or email us and describe the job.
The process
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours in a single home in most cases. For a village or hamlet like Calvert, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints

Aftercare tips
So the new joints stay in good condition:
- Check bath and shower seals every few months as the house settles
- Follow the cure time we give you
- Resist patching a failed seal with a tube from the DIY shop
- Ventilate bathrooms well, especially in the first year
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day before water reaches them.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
