Aftercare tips

So the new joints stay in good condition:

  • Record problems with dated pictures
  • Keep water off fresh sealant until it has cured
  • Wipe joints with warm soapy water
  • Don’t wait for the house to settle if water is getting through

Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day.

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

How we handle new build mastic in Lacey Green

We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that’s what rushed new-build sealant usually lacks. We work on windows & doors, plot handovers and skirting & floors, and the jobs we see most are frame joints opening as the plaster dries and cracks appearing as a new home settles.

For a small place like Lacey Green, the journey and access are planned in advance, and the work itself is the same as on any site.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Do you need new build mastic in Lacey Green?

Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry before the sealant goes on.

Most people get in touch after spotting something like this:

  • Smeared, uneven beads picked up at snagging
  • Sealant work across a run of new homes
  • Sealant applied over dusty or wet surfaces
  • Cracked sealant around new window and door frames

For new homes near Saunderton station, it’s worth checking the sealant early, while snags are still fresh.

Questions to ask before you book

  • What insurance they hold
  • Whether all the old sealant comes out first
  • What happens if the job turns out different
  • What the quote includes, VAT included or not

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

DIY sealant or a professional job?

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.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Lacey Green: your questions answered

Do you cover Lacey Green for new build mastic?

Yes, Lacey Green is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.

Is Lacey Green within the area you cover?

Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Why has my new-build shower seal failed already?

A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.

What do you put in the joint?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

How long does the job take?

It depends on the size of the job, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We will give you a better idea when we quote.

Do you take on second-fix sealing for builders?

Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we’ll quote.

Do I need to be at home?

It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
