New build mastic near Old Malden

New build mastic in Old Malden

We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. If you are dealing with sealant work across a run of new homes and sealant that never bonded to the surface, we can help, whatever the surface.

In smaller places like Old Malden, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.

Our work is backed for twelve months.

Should I try it myself first?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Why deal with it now?

Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot. Around Old Malden, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

  • Homes, businesses and hotels
  • 12-month guarantee on every job

Can you work from my snagging list?

Is it messy?

Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

Do I need to be at home?

That depends on where the joints are. Inside work needs someone to give us access.

Why does sealant fail so quickly in new builds?

A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.

How the job changes by surface

Kitchens

Beside the sink, the joint takes water every day. We use a sealant suited to kitchens.

Bathrooms and en suites

Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out with baths filled first.

Quotes for new build mastic in Old Malden

Jobs vary more than people expect. The main factors:

  • Whether old sealant or filler has to be cut out
  • Any working-time requirements on site
  • Which sealant suits the joint
  • Mould in or behind the old joints

The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.

Asking for a quote

To help us quote quickly, please include:

  • How many joints, rooms or windows are involved
  • Whether it has been sealed before
  • Where the job is, and your postcode
  • What’s wrong with the joints now

If you’re in Old Malden and need new build mastic, call 0345 464 0079 or drop us an email. Tell us what the problem is and where, and you’ll get a clear quote before work begins.

How the visit works

There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours for most snagging lists, longer for a run of plots in most cases. In a smaller place like Old Malden, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. The failed sealant is removed completely down to clean surfaces.
  3. We clean out the dust and grit left from the build.
  4. We prime where needed and apply a sealant suited to each joint.
  5. We tool every joint neatly and tell you when each area can be used.

Preparing for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Keep children and pets away from the work area
  • Let us know about parking restrictions

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. Our tips:

  • Record problems with dated pictures
  • Keep water off fresh sealant until it has cured
  • Clean sealant with mild detergent, not abrasives
  • Look at the sealant regularly in the first couple of years

Don’t stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.

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.

What sealant work can’t fix

A few problems are outside what sealant work can do:

  • Movement caused by a poorly fitted tray or bath
  • Deciding who is responsible under a builder’s warranty
  • Structural cracks in walls or ceilings

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.
