Granborough questions

Do you cover Granborough for new build mastic?

Yes. We work across London and the South East, and Granborough is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.

Do you cover smaller places like Granborough?

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

Can you work on commercial sites?

Yes. We have worked for hotels, offices and other businesses and we are fully insured.

Are you insured?

Yes. We’re fully insured.

Which products do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.

Should I wait before resealing?

Where water is getting through, don’t wait. Small gaps that are just cosmetic can be resealed once movement has slowed.

Can landlords and businesses book you?

Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.

Can new sealant go on top of the old bead?

No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.

New build mastic for homes and businesses in Granborough

A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. If you are dealing with sealant that never bonded to the surface and kitchen sealant that has pulled off the wall, we can put it right.

Somewhere as small as Granborough, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.

Whatever the size of the job, you get the same 12-month guarantee in Granborough and across Buckinghamshire.

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Follow the cure time we give you
  • Keep pictures and emails about snagging items
  • Avoid running a DIY bead over the old one
  • Act quickly if a seal starts to leak

Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.

Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.

What new build mastic looks like in Granborough

The process

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the number of plots and we leave things clean and tidy. For a village or hamlet like Granborough, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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. The old bead comes out in full, with no layer left behind.
  3. We clean off dust from the build and prime the surfaces where the product needs it.
  4. We apply a sealant that suits each joint and tool it to a neat finish.
  5. Each area is checked and left with its cure time.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • For business premises, tell us about site rules or sign-in
  • Let us know about earlier repairs to the joints

How the job changes by surface

Kitchens

Sink joints are wet all the time. A kitchen sealant goes in there suited to the job.

Plot handovers

Send us the schedule and any sealant specification and we will quote. Sealant work across the plot is covered.

How we quote for new build mastic

The price is agreed before any work begins. It takes into account:

  • The size of the job
  • The product the joint needs
  • How many areas need sealing
  • How much old sealant there is and how hard it is to remove

Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.

What we need to know

To make quoting easier, let us know:

  • Whether it has been sealed before
  • Roughly how big the job is
  • If it’s domestic, commercial or a hotel
  • The problem you’ve noticed

We don’t publish a price list. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or send us an email.

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 Granborough, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
