New build mastic for homes and businesses in Rivenhall

Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. We work on bathrooms & en suites, windows & doors and show homes, and common reasons people get in touch are cracked sealant around new window and door frames and gaps behind new kitchen upstands.

Somewhere as small as Rivenhall, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

What happens if it’s left?

Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Around Rivenhall, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.

Why Rivenhall customers choose us

  • Any old sealant cut out fully, not covered over
  • Over 20 years’ experience
  • A sealant colour to suit the surroundings
  • Neat joints and a tidy finish

See our cost guide or customer reviews.

Looking after it afterwards

Good habits help new joints last longer. Our tips:

  • Wipe joints with warm soapy water
  • Avoid running a DIY bead over the old one
  • Wait for the cure time before using a resealed shower
  • Photograph failed sealant before it’s redone

Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.

The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.

What affects the quote in Rivenhall

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • The product the joint needs
  • How many areas need sealing
  • Access and height
  • When we can work, for business premises

The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

Helping us quote

Photos help, but a description is a good start. Try to tell us:

  • A few photos by email, if you can
  • What the problem is, such as mould, gaps, leaks or cracking
  • The rough size of the job
  • Where the job is, and your postcode

For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work.

Your questions about new build mastic in Rivenhall

Can you help a landlord with a rental near Witham station?

Yes. We work for landlords and agents as well as homeowners. You can ring 0345 464 0079 or email us with the details for a clear quote.

Can you do new build mastic in Rivenhall?

Yes. We work across London and the South East, and Rivenhall is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.

How long should I leave it?

Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.

Will you just run a new bead over the existing one?

No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.

Will you leave a mess?

No. The area is protected while we work and cleaned up afterwards.

Is there a guarantee?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.

How do I get a quote for new build mastic in Rivenhall?

We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

What do you need from me for a quote?

Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or email us.

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

Surface by surface

Show homes

We seal show-home bathrooms, kitchens and frames ready for viewings. Tell us when the home is open so we can plan around it.

Skirting and floors

Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.

New homes and floors in Rivenhall

When something else is needed

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

  • Your warranty claim itself, which is between you and the builder
  • A tray or bath that is not properly supported, until it’s fixed
  • Leaks from pipes, valves or wastes, which need a plumber

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

What we do, step by step

Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of plots. In a small place like Rivenhall, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each joint is checked for movement before we start.
  2. We remove the failed sealant and clean the joints.
  3. We make sure the joints are dry and prime them if needed.
  4. New sealant goes in, with baths filled first so they’re at their heaviest.
  5. The finished joints are checked and the cure times given.

Before we arrive

  • Let us know about parking restrictions
  • Let us know about earlier repairs to the joints
  • For business premises, tell us about site rules or sign-in
