New build mastic for homes and businesses in Effingham
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on plot handovers, show homes and bathrooms & en suites, and the jobs we see most are beads laid onto grit and dust from the build and internal frame sealant that has split.
In a village or hamlet like Effingham, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Whatever the size of the job, it’s backed by our 12-month guarantee in Effingham and across Surrey.

Landlords, agents and businesses in Effingham
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
How the visit works
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. In a small place like Effingham, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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 down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property

What affects the cost of new build mastic
We do not publish a price list. The quote depends on:
- When we can work, for business premises
- Whether there’s mould to deal with
- The number and length of the joints
- Whether the work is at height
Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Pictures of the joints, sent by email
- How we’d reach the joints
- If someone has resealed it before
- The problem you’ve noticed
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.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

How to look after the new joints
To keep the joints looking good and working properly:
- Don’t seal over failed sealant yourself
- Clean sealant with mild detergent, not abrasives
- Check bath and shower seals every few months as the house settles
- Use the extractor fan every time you shower
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
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.

Should I wait before resealing?

Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you will get one quote.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
What the job involves on each surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
When to call us in Effingham
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry first.
The most common problems we see are:
- Smeared, uneven beads picked up at snagging
- Cracks appearing as a new home settles
- Sealant work across a run of new homes
- Sealant applied over dusty or wet surfaces
For new homes near Bookham station, it’s worth checking the sealant early, while snags are still fresh.
