New build mastic near Cudham

How the job changes by surface

Windows and doors

A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.

Kitchens

Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.

New build mastic for homes and businesses in Cudham

A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. Typical jobs include leaking shower tray seals in a new home and untidy sealant flagged on a snagging list, across skirting & floors, show homes and windows & doors.

Somewhere as small as Cudham, 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.

We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Your questions about new build mastic in Cudham

Can you do new build mastic in Cudham?

Yes. Our work covers London and the South East, and Cudham is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.

Will you come out to Cudham?

Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Can you do plot mastic on a new development?

Yes. We work through plots to your schedule. Tell us the plots and the joints involved for a clear quote.

Do I need to be at home?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Where is Mr Mastic based?

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.

Can landlords and businesses book you?

Yes, often. We can quote for several properties at once.

Why has my new-build shower seal failed already?

Cracking in the first couple of years is common. Rushed application on dusty surfaces makes it worse.

Should I go to my builder first?

While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix doesn’t last, we can help.

Landlords, agents and businesses in Cudham

We regularly work with letting and managing agents. Tell us the address, the job and how access works.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

Leave it or put it right?

A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Around Cudham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Combining jobs into one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.

Common problems we fix in Cudham

Sealant applied onto damp surfaces does not bond well. Site programmes do not always leave time for joints to dry.

Keep an eye out for these signs:

  • Untidy sealant flagged on a snagging list
  • Sealant that never bonded to the surface
  • Second-fix sealing on new plots
  • Gaps behind new kitchen upstands

For new homes near Chelsfield station, it’s worth checking the sealant early, while snags are still fresh.

What your quote should include

  • Which colour the sealant will be
  • How hidden problems are handled
  • Is the old sealant removed completely?
  • What insurance they hold

Choosing a sealant specialist

New homes and floors in Cudham

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

When something else is needed

To be straight with you, some problems need a different trade:

  • Baths and trays that move too much for sealant to cope with
  • Your warranty claim itself, which is between you and the builder
  • Cracked trays, tiles or worktops

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

Surfaces we seal

  • Kitchens
  • Windows & doors
  • Plot handovers
  • Skirting & floors
  • Show homes
  • Bathrooms & en suites

Can I do it myself?

The difference is mostly in the preparation and the 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.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

What happens on the day

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Cudham, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Each joint is checked for movement before we start.
  2. Old sealant is cut out and the joints cleaned.
  3. Joints are dried and primed where the product calls for it.
  4. New sealant goes in, with baths filled first so they’re at their heaviest.
  5. The finished joints are checked and the cure times given.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Let us know if you’ve seen damp or leaks
  • Tell us about any previous sealing or DIY attempts
