New build mastic near Bunkers Hill

Should I try it myself first?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

New build mastic in Bunkers Hill

Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. If you are dealing with sealant applied over dusty or wet surfaces and messy sealant that spoils new finishes, we can put it right, whatever the surface.

In a village or hamlet like Bunkers Hill, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

There’s a 12-month guarantee on every job, whatever its size.

Signs you need new build mastic in Bunkers Hill

  • Skirting joints opening in the first winter
  • Sealant work across a run of new homes
  • Frame joints opening as the plaster dries
  • Beads laid onto grit and dust from the build

Our hiring checklist

What happens on the day

At the end, we look at the finished work together and explain the cure time. The work normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. Somewhere as small as Bunkers Hill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. Every bit of the old builder’s sealant is cut out.
  3. We clean out the dust and grit left from the build.
  4. Primer goes on where the surface and product need it, then the new sealant.
  5. We tool every joint neatly and tell you when each area can be used.

Before we arrive

  • Move anything stored near the joints
  • Keep children and pets away from the work area
  • Tell us about access, such as stairs, a lift or high-level joints

Advice

Quotes for new build mastic in Bunkers Hill

We quote each job individually. This is what makes a difference:

  • The number of rooms or windows
  • The number and length of the joints
  • The old material and how stubborn it is
  • The type of sealant required

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What to tell us for a quote

When you call or email, it’s useful to know:

  • The address or postcode of the job
  • A few photos by email, if you can
  • Any previous sealing or DIY work
  • The rough size of the job

For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved and send you a clear quote.

Different surfaces, different methods

Show homes

We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.

Bathrooms and en suites

Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Raise failed sealant with the developer while you are covered
  • Check bath and shower seals every few months as the house settles
  • Open a window or run the fan after bathing
  • Follow the cure time we give you

Don’t stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.

A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
