New build mastic in Warborough, done properly

New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Typical jobs include cracked sealant around new window and door frames and untidy sealant flagged on a snagging list, across plot handovers, bathrooms & en suites and skirting & floors.

Older homes in small places like Warborough often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.

A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

FAQs for Warborough

Is Warborough within the area you cover?

Yes, Warborough is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

I let a flat near Culham station. Can you help?

Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.

How long should I leave it?

Cure times vary by product and the temperature. We tell you how long to leave it before we go.

Where is Mr Mastic based?

We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.

What colour sealant will you use?

That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before any work starts.

Do you hold any approvals?

Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.

What information do you need?

Let us know what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.

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

No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.

Why act early in Warborough

It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. Older cottages and farmhouses around Warborough can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

Why choose Mr Mastic in Warborough

  • Colour agreed with you before any work starts
  • White, clear, grey or coloured to suit, where the product allows
  • Quality sealants from Arbo and Everbuild
  • A sealant colour to suit the surroundings

How we quote for new build mastic

We don’t publish a price list, because no two jobs are the same. What we look at:

  • The number and length of the joints
  • How easy the joints are to reach
  • Mould in or behind the old joints
  • When we can work, for business premises

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Helping us quote

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

  • The rough size of the job
  • Any access issues, like height or stairs
  • Whether it has been sealed before
  • Whether it’s a home or a business

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.

When it isn’t the sealant

In fairness, there are a few things sealant will not fix:

  • Cracked trays, tiles or worktops
  • Settlement cracks that need a surveyor
  • Movement caused by a poorly fitted tray or bath

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

Joints and surfaces we work on

  • Windows & doors
  • Skirting & floors
  • Kitchens
  • Plot handovers
  • Show homes
  • Bathrooms & en suites

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.

Should I try it myself first?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

How it works

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the number of plots. In a small place like Warborough, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at why each joint failed, including any movement.
  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. We check every joint and leave you with the cure times.

Before we arrive

  • On commercial sites, let us know about site rules
  • Move anything stored near the joints
  • Let us know if you’ve seen damp or leaks

Getting a quote

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

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. We suggest:

  • Get a leaking seal dealt with right away
  • Avoid scourers and strong chemicals on sealant
  • Open a window or run the fan after bathing
  • Check bath and shower seals every few months as the house settles

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

Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
