New build mastic in Ruislip Manor

Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. If you’re dealing with shower seals failing in the first year or two and cracks appearing as a new home settles, we can put it right.

Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.

A 12-month guarantee comes as standard, so you’re covered after we have gone.

Can I do it myself?

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, and the work is guaranteed for a year.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

New build mastic in Ruislip Manor: local notes

Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For new homes near West Ruislip station, it’s worth checking the sealant early, while snags are still fresh. As a London address, Ruislip Manor can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Looking after it afterwards

A little care helps the new joints last. We recommend:

  • Get a leaking seal dealt with right away
  • Raise failed sealant with the developer while you’re covered
  • Don’t seal over failed sealant yourself
  • Watch for new gaps as the house dries out

Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.

Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.

What we can’t put right

We’ll always be straight with you, so here’s what new sealant will not do:

  • Disputes or warranty claims with your builder
  • Baths and trays that move too much for sealant to cope with
  • Damaged fittings that need replacing

If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Landlord and commercial work in Ruislip Manor

We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Why act early in Ruislip Manor

Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Ruislip Manor, the repair is bigger than a sealant job.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

Why Ruislip Manor clients choose us

Your questions about new build mastic in Ruislip Manor

Is parking a problem for a job in Ruislip Manor?

Parking in Ruislip Manor, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.

Do you cover Ruislip Manor for new build mastic?

Yes, Ruislip Manor is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.

When is the best time to reseal in a new build?

Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.

Can you work from my snagging list?

Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before work begins.

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint before resealing.

What information do you need?

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

Do you work for hotels and businesses?

Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.

Can you reseal over the builder’s sealant?

No. New silicone will not bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.

What we do, step by step

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on the number of plots. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. We look at why each joint failed, including any movement.
  2. Old sealant is cut out and the joints cleaned.
  3. We make sure the joints are dry and prime them if needed.
  4. Baths are filled with water, then the new sealant is applied.
  5. We check every joint and leave you with the cure times.

How to prepare

  • Let us know about earlier repairs to the joints
  • Let us know if you’ve seen damp or leaks
  • Clear the area around the work
