Aftercare tips

Aftercare is simple, and it makes a real difference:

  • Follow the cure time we give you
  • Raise failed sealant with the developer while you are covered
  • Avoid scourers and strong chemicals on sealant
  • Resist patching a failed seal with a tube from the DIY shop

Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.

The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left in a busy bathroom.

New build mastic in Itchen Abbas

Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a seal that is letting water through needs doing now. We work on skirting & floors, kitchens and bathrooms & en suites, and common reasons people get in touch are internal frame sealant that has split and kitchen sealant that has pulled off the wall.

Work in a small place like Itchen Abbas just needs the journey and access planning, and the work itself is the same as on any site.

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

Different surfaces, different methods

Bathrooms and en suites

En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.

Skirting and floors

As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.

What we’re called out for in Itchen Abbas

A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that cannot keep up splits.

The most common problems we see are:

  • Gaps between new skirting and floors
  • Smeared, uneven beads picked up at snagging
  • Cracks appearing as a new home settles
  • Beads laid onto grit and dust from the build

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

Questions to ask before booking

  • How the joint is cleaned and prepared
  • When the joint can take water or movement
  • What product goes in the joint
  • How the colour is chosen

Our hiring checklist

When something else is needed

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

  • Plumbing faults behind the sealant
  • Disputes or warranty claims with your builder
  • Structural cracks in walls or ceilings

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

What to tell us for a quote

Can I do it myself?

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

The process

When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere like Itchen Abbas needs a little journey planning: 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. First we work through your snagging list or plot schedule with you.
  2. We cut out every bit of the failed or messy sealant.
  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.

Preparing for the visit

  • Let us know about parking restrictions
  • Tell us about any previous sealing or DIY attempts
  • Keep children and pets away from the work area

Itchen Abbas: your questions answered

Will you come out to Itchen Abbas?

Yes. Itchen Abbas is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Is Itchen Abbas in your area for new build mastic?

Can I send you my snagging list?

Yes. Send us the sealant items on the list, with pictures if you can and we will give you a quote. We’ll flag anything that needs another trade.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.

Why does sealant fail so quickly in new builds?

Lots of new homes see sealant crack early, because the house is drying and settling. Poor preparation at handover adds to it.

Will it make a mess?

No. We work neatly, protect the area around the joints and tidy up afterwards.

When is the sealant fully cured?

Cure times vary by product and the conditions. We tell you how long to leave it before we go.

When is the best time to reseal in a new build?

It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
