New build mastic for Enfield homes and businesses

Should I try it myself first?

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

About our new build mastic in Enfield

For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. Typical jobs include shower seals failing in the first year or two and second-fix sealing on new plots, across plot handovers, bathrooms & en suites and show homes.

New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Landlords, agents and businesses in Enfield

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

How it works

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes a few hours in a single home. In a London area like Enfield, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  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. Each joint is cleaned of dust and grit, then primed if required.
  4. A sealant chosen for each area goes in and is tooled smooth.
  5. We check every joint and tell you how long each needs to cure.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Keep pets and children clear of the area while we work
  • Tell us if parking is tricky

When to call us in Enfield

The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Both fail early.

People generally contact us when they notice one of these:

  • Smeared, uneven beads picked up at snagging
  • Gaps behind new kitchen upstands
  • Cracked sealant around new window and door frames
  • Skirting joints opening in the first winter

If you’ve bought a new home near Enfield Town station, the sealant around baths, showers and frames is worth checking in the first year or two.

10 questions to ask before you book

What affects the quote in Enfield

We quote each job individually. These are the things that affect it:

  • The size of the job
  • How many areas need sealing
  • The product the joint needs
  • The old material and how stubborn it is

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

Asking for a quote

When you call or email, it’s useful to know:

  • The problem you’ve noticed
  • Any access issues, like height or stairs
  • Any previous sealing or DIY work
  • Pictures of the joints, sent by email

If you are in Enfield and need new build mastic, call 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.

When it is not the sealant

To be straight with you, some problems need a different trade:

  • Structural cracks in walls or ceilings
  • Your warranty claim itself, which is between you and the builder
  • Leaks from pipes, valves or wastes, which need a plumber

If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

Joints and surfaces we work on

  • Bathrooms & en suites
  • Plot handovers
  • Show homes

Surface by surface

Kitchens

As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.

Show homes

We seal show-home bathrooms, kitchens and frames ready for viewings. We will plan around viewing times.

Enfield questions

Is parking a problem for a job in Enfield?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

Do you work for landlords with property near Enfield Town station?

Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.

What do you need from me for a quote?

Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or email us.

Does someone need to be in?

We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.

Do you do commercial work?

Yes. Hotels, offices and other businesses use us, and we’re fully insured.

Is it messy?

We keep the work tidy. Nearby surfaces are protected.

Where are you based?

Mr Mastic is based in Crawley. Our applicators cover Enfield, along with the rest of our area.

Should I wait before resealing?

For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
