Trusted new build mastic in Northington

Different surfaces, different methods

Show homes

Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.

Skirting and floors

Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.

How we handle new build mastic in Northington

For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on skirting & floors, plot handovers and windows & doors, and people most often call us about second-fix sealing on new plots and cracks appearing as a new home settles.

Older homes in small places like Northington often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

All of our work is guaranteed for twelve months, in Northington and everywhere else we cover.

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

Choosing a sealant specialist

How it works

We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours in a single home. In a small place like Northington, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at why each joint failed, including any movement.
  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. We check every joint and leave you with the cure times.

Before we arrive

  • Let us know about stairs, lifts or work at height
  • Tell us if parking is tricky
  • Let us know if you’ve seen damp or leaks

What sealant work cannot fix

We’d rather tell you now than do work that will not last, so these are the limits:

  • Damaged fittings that need replacing
  • Your warranty claim itself, which is between you and the builder
  • Baths and trays that move too much for sealant to cope with

If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

Where we work in Northington

  • Windows & doors

Looking after it afterwards

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

  • Open a window or run the fan after bathing
  • Put sealant faults on your snagging list early
  • Check bath and shower seals every few months as the house settles
  • Wipe joints with warm soapy water

Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.

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.
