New build mastic in Bulstrode

Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. Typical jobs include plot mastic for developers ahead of handover and new-build shower sealant that has already split, across show homes, kitchens and windows & doors.

Work in a small place like Bulstrode just needs the journey and access planning, and once on site, the job is the same as anywhere.

Every job is covered by a one-year guarantee, wherever you are in Hertfordshire.

Do you need new build mastic in Bulstrode?

Sealant applied onto damp surfaces doesn’t bond well. Site programmes don’t always leave time for joints to dry first.

The problems people normally mention when they call are:

  • Smeared, uneven beads picked up at snagging
  • Sealant that never bonded to the surface
  • Leaking shower tray seals in a new home
  • Joints pulling apart as timber shrinks

Around Bulstrode, as everywhere, new build mastic is only as good as the preparation behind it.

Keeping the joints in good condition

Aftercare is simple, and it makes a real difference:

  • Follow the cure time we give you
  • Look at the sealant regularly in the first couple of years
  • Avoid running a DIY bead over the old one
  • Act quickly if a seal starts to leak

Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.

Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.

What we cannot put right

Some problems need a builder, plumber or other trade rather than us:

  • Plumbing faults behind the sealant
  • Structural cracks in walls or ceilings
  • Movement caused by a poorly fitted tray or bath

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

  • Windows & doors
  • Show homes
  • Bathrooms & en suites

DIY versus a professional finish

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you’ve already had a go yourself, that is fine. We cut it out and start again.

The process

At the end, we look at the finished work together. 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 Bulstrode, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your snagging list or plot schedule with you.
  2. Failed or untidy sealant is cut out completely.
  3. We clean off dust from the build and prime the surfaces where the product needs it.
  4. A sealant chosen for each area goes in and is tooled smooth.
  5. We check every joint and tell you how long each needs to cure.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • Try not to wet indoor joints just before the visit
  • Mention any parking rules near the property

Advice

Leave it or put it right?

Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. In a small place like Bulstrode, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Why book with us

  • Tidy, careful work
  • We never seal over old sealant
  • Colour agreed with you before any work starts
  • Domestic, commercial and hotel work

Surface by surface

Kitchens

As a new house dries, worktops and walls shift a little, which opens gaps along the back. A fresh flexible bead closes them.

Bathrooms and en suites

En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
