How we handle new build mastic in Sleaford
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you have cracked caulk along new skirting and internal frame sealant that has split, we can put it right, whatever the surface.
Somewhere as small as Sleaford, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

When to call us in Sleaford
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
It’s worth asking for a quote if you see:
- Worktop and upstand sealant coming away
- Cracked caulk along new skirting
- Cracked sealant around new window and door frames
- Sealant applied over dusty or wet surfaces
If you’ve bought a new home near Bentley (Hampshire) station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- Who does the work, and how experienced they are
- What product goes in the joint
- Is VAT in the price?
- The length of the guarantee
What the job involves on each surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
Aftercare tips
To keep the joints looking good and working properly:
- Record problems with dated photos
- Open a window or run the fan after bathing
- Wipe joints with warm soapy water
- Wait for the cure time before using a resealed shower
Don’t stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
What we can’t put right
We will always be straight with you, so here’s what new sealant won’t do:
- Baths and trays that move too much for sealant to cope with
- Settlement cracks that need a surveyor
- Disputes or warranty claims with your builder
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the number of plots. In a small place like Sleaford, access is normally 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.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height

Advice
Your questions about new build mastic in Sleaford
Will you come out to Sleaford?
Yes. Sleaford is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Bentley (Hampshire) station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
My new home is still under warranty. Should I contact you?
Your builder, if you are still in their snagging or warranty period. If that doesn’t work out, we’re happy to quote.
Do you work through snagging lists?
Yes. Send the list and a few pictures of the sealant items, and we will quote. We’ll tell you if anything on it isn’t a sealant job.
Why it’s worth doing now in Sleaford
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot. In a small place like Sleaford, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why book with us
- Tidy, careful work
- Experience in homes, commercial sites and hotels
- An ARBOMaster approved applicator
- A sealant colour to suit the surroundings
