New build mastic near Sindlesham

New build mastic in Sindlesham

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. We work on kitchens, windows & doors and skirting & floors, and people most often call us about untidy sealant flagged on a snagging list and gaps between new skirting and floors.

Older homes in small places like Sindlesham often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.

You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Honest limits

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

  • Your warranty claim itself, which is between you and the builder
  • Broken tiles or a split tray
  • 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 booking.

Where we work in Sindlesham

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

Why deal with it now?

If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. In a small place like Sindlesham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and send you a clear quote before any work starts.

Joints and finishes in Sindlesham homes

The process

Before we leave, we go over the finished joints with you. The work normally takes a few hours in a single home, depending on the size of the job. Somewhere like Sindlesham needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
  2. Failed or untidy sealant is cut out completely.
  3. Surfaces are cleaned of building dust and primed where needed.
  4. New sealant suited to each joint is applied and tooled neatly.
  5. Finally, each room is checked and you are given the cure time.

How to prepare

  • Let us know about earlier repairs to the joints
  • On commercial sites, let us know about site rules
  • Move anything stored near the joints

When to call us in Sindlesham

Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.

Keep an eye out for these signs:

  • Smeared, uneven beads picked up at snagging
  • Cracked sealant around new window and door frames
  • Joints pulling apart as timber shrinks
  • Shower seals failing in the first year or two

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

What to look for in a quote

  • How the joint is cleaned and prepared
  • Which sealant they’ll use, and why
  • Which colour the sealant will be
  • What insurance they hold

How to choose a mastic man

How the job changes by surface

Show homes

We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.

Windows and doors

Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one that suits the frame.

How to look after the new joints

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Raise failed sealant with the developer while you’re covered
  • Open a window or run the fan after bathing
  • Do not seal over failed sealant yourself
  • Keep photos and emails about snagging items

Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.

Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.

Common questions in Sindlesham

Is Sindlesham in your area for new build mastic?

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

Do you cover smaller places like Sindlesham?

Yes, Sindlesham is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Can you do several jobs on one visit?

Yes, and it often makes sense. Doing several areas at once is normally more efficient.

When is the sealant fully cured?

Different products cure at different speeds, so follow the cure time we give you when we finish.

Can you work from my snagging list?

Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before we start.

Do you work for letting agents?

Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.

Will it make a mess?

Tidy work is part of the job. We protect what’s around the joints.

Will there be a smell?

Possibly a little. It fades as the sealant cures, and ventilation helps.
