About our new build mastic in Streatley

In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. Common call-outs are for messy sealant that spoils new finishes and new-build shower sealant that has already split, on skirting & floors, show homes and windows & doors.

Around Streatley, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

All of our work is guaranteed for twelve months, in Streatley and everywhere else we cover.

Landlords, agents and businesses in Streatley

We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.

When it is not the sealant

It helps to know what we can’t do too:

  • Structural cracks in walls or ceilings
  • Broken tiles or a split tray
  • Baths and trays that move too much for sealant to cope with

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

Surfaces we seal

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

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Common problems we fix in Streatley

The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.

Most people get in touch after spotting one of these:

  • Sealant that never bonded to the surface
  • Untidy sealant flagged on a snagging list
  • Shower seals failing in the first year or two
  • Joints pulling apart as timber shrinks

For new homes near Goring & Streatley station, it’s worth checking the sealant early, while snags are still fresh.

10 questions to ask before booking

Common questions in Streatley

Can you help a landlord with a rental near Goring & Streatley station?

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

Is Streatley within the area you cover?

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.

Is the work guaranteed?

Yes, for a year. If anything is not right with the work within the year, let us know and we will sort it.

How long does the job take?

It depends on the size of the job, but most jobs take a few hours for most snagging lists, longer for a run of plots. We will give you a better idea when we quote.

Who should fix failed sealant in a new build?

Start with your builder while their snagging or warranty period runs. If that does not work out, we’re happy to quote.

Does someone need to be in?

That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

What do you need from me for a quote?

Just the basics: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or send us an email.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.

Joints and finishes in Streatley homes

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Keeping the joints in good condition

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

  • Resist patching a failed seal with a tube from the DIY shop
  • Photograph failed sealant before it’s redone
  • Clean sealant with mild detergent, not abrasives
  • Put sealant faults on your snagging list early

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

A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.

The process

At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. In a small place like Streatley, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start by going through the snagging items or plot schedule with you.
  2. Every bit of the old builder’s sealant is cut out, with no layer left behind.
  3. We clean out the dust and grit left from the build.
  4. We prime where needed and apply a sealant suited to each joint.
  5. Each bead is tooled and the cure times explained.

Getting ready for the visit

  • Mention any parking rules near the property
  • Let us know about stairs, lifts or work at height
  • Plan for the work area to be out of bounds to pets and children
