New build mastic near Dunn Street

About our new build mastic in Dunn Street

If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. We work on plot handovers, windows & doors and skirting & floors, and people most often call us about internal frame sealant that has split and gaps behind new kitchen upstands.

Somewhere as small as Dunn Street, 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.

Every job is covered by our one-year guarantee, wherever you are in Medway.

Why act early in Dunn Street

DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around Dunn Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

Why us?

  • ARBOMaster approved applicator
  • Tidy, careful work
  • Anti-fungal silicone where joints get wet
  • Colour agreed with you before work begins

How it works

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Dunn Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each joint is checked for movement before we start.
  2. We remove the failed sealant and clean the joints.
  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

  • Plan for the work area to be out of bounds to pets and children
  • Let us know about earlier repairs to the joints
  • Mention any parking rules near the property

Related advice

Landlords, agents and businesses in Dunn Street

Housing providers, facilities teams and property managers book us too in Dunn Street and across Medway. We can quote a run of properties together, and we’re fully insured.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Keeping the joints in good condition

Aftercare is simple, and it makes a real difference:

  • Look at the sealant regularly in the first couple of years
  • Use the extractor fan every time you shower
  • Record problems with dated photos
  • Do not seal over failed sealant yourself

Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.

Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.

Different surfaces, different methods

Kitchens

New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.

Bathrooms and en suites

Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in.

When to call us in Dunn Street

Sealant applied onto damp surfaces does not bond well. On a busy site, joints are not always given time to dry first.

It’s worth asking for a quote if you see:

  • Joints pulling apart as timber shrinks
  • Sealant work across a run of new homes
  • Kitchen sealant that has pulled off the wall
  • Untidy sealant flagged on a snagging list

In and around Dunn Street, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Questions to ask before booking

  • What product goes in the joint
  • How hidden problems are handled
  • Whether they’re fully insured
  • Is the old sealant removed completely?

Our hiring checklist

When it is not the sealant

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Damaged fittings that need replacing
  • Your warranty claim itself, which is between you and the builder
  • Leaking fittings rather than failed sealant

Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.
