New build mastic for homes and businesses in Slaugham
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. We work on bathrooms & en suites, skirting & floors and kitchens, and people most often call us about gaps behind new kitchen upstands and cracked caulk along new skirting.
Older homes in small places like Slaugham often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work is covered by a 12-month guarantee.

Surface by surface
Plot handovers
Developers can send the plot schedule and specification and we’ll quote. We seal bathrooms, kitchens, frames and floors.
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Deciding who is responsible under a builder’s warranty
- Structural cracks in walls or ceilings
- Movement caused by a poorly fitted tray or bath

Slaugham questions
Will you come out to Slaugham?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Slaugham in your area for new build mastic?
Yes, Slaugham is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear quote.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you guarantee your work?
Yes. There’s a 12-month guarantee on every job, large or small.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Why has my new-build shower seal failed already?
It’s common, and there are normally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.

How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- Any working-time requirements on site
- The product the joint needs
- Mould in or behind the old joints
- How many areas need sealing
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- The rough size of the job
- How we’d reach the joints
- What’s wrong with the joints now
- Photos by email, if that’s easy
Getting a quote is simple: let us know what needs doing and where. Photos by email help us understand the job.
Keeping the joints in good condition
Looking after new joints is easy:
- Open a window or run the fan after bathing
- Avoid scourers and strong chemicals on sealant
- Report sealant problems to your builder during the snagging period
- Wait for the cure time before using a resealed shower
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.

Do you need new build mastic in Slaugham?
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.
Any of these means the joints need attention:
- Frame joints opening as the plaster dries
- Gaps between new skirting and floors
- Beads laid onto grit and dust from the build
- Plot mastic for developers ahead of handover
In and around Slaugham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- What product goes in the joint
- What the quote includes, VAT included or not
- Whether they seal over old material or remove it
- What happens if the job turns out different
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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 fails, we can still redo it.
What we do, step by step
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Slaugham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
