Trusted new build mastic in Passfield

New build mastic in Passfield

A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on bathrooms & en suites, skirting & floors and plot handovers, and people most often call us about worktop and upstand sealant coming away and shower seals failing in the first year or two.

For a small place like Passfield, the journey and access are planned in advance, and once on site, the job is the same as anywhere.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Aftercare tips

A little care helps the new joints last. Our advice:

  • Do not wait for the house to settle if water is getting through
  • Put sealant faults on your snagging list early
  • Wait for the cure time before using a resealed shower
  • Record problems with dated pictures

Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.

Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.

Why deal with it now?

Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a small place like Passfield, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

How the job changes by surface

Kitchens

New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.

Windows and doors

The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.

What sealant work can’t fix

In fairness, some problems need a different trade:

  • Damaged fittings that need replacing
  • Plumbing faults behind the sealant
  • Baths and trays that move too much for sealant to cope with

Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.

Surfaces we seal

  • Skirting & floors
  • Plot handovers
  • Windows & doors

How the visit works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours in a single home, and the area is left clean. Somewhere like Passfield needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We start by going through the snagging items or plot schedule with you.
  2. The failed sealant is removed completely, with no layer left behind.
  3. Joints are vacuumed and cleaned of building dust.
  4. We prime where needed and apply a sealant suited to each joint.
  5. We tool every joint neatly and tell you when each area can be used.

Advice

Passfield questions

Can you do new build mastic in Passfield?

Yes. Our work covers London and the South East, and Passfield 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 Passfield?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Why does sealant fail so quickly in new builds?

There are normally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.

What do you put in the joint?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

I rent my home. Can I book you?

We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.

Do you have insurance?

Yes. We’re fully insured.

Can you do plot mastic on a new development?

Yes. We seal plots to the developer’s programme, room by room. Tell us the plots and the joints involved for a clear quote.

What does new build mastic cost?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
