What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Boxted, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- 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.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules
- Clear items away from the joints we are working on

How we handle new build mastic in Boxted
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on bathrooms & en suites, plot handovers and show homes, and common reasons people get in touch are sealant work across a run of new homes and cracks appearing as a new home settles.
Around Boxted, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Every job is covered by our 12-month guarantee, wherever you are in Essex.

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Surface by surface
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Cracking that points to a structural problem
- Movement caused by a poorly fitted tray or bath
- Broken tiles or a split tray
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
Surfaces we seal
- Windows & doors
- Plot handovers
- Bathrooms & en suites
- Show homes
- Skirting & floors
- Kitchens
Keeping the joints in good condition
So the new joints stay in good condition:
- Put sealant faults on your snagging list early
- Act quickly if a seal starts to leak
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.

Do you need new build mastic in Boxted?
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry first.
If you can see any of these, it’s time to have the joints looked at:
- Internal frame sealant that has split
- Messy sealant that spoils new finishes
- Skirting joints opening in the first winter
- Shower seals failing in the first year or two
In and around Boxted, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
