How the job changes by surface

Commercial and mixed-use buildings

Commercial occupiers normally stay open during the work so the work is phased.

Estate-wide resealing programmes

Using the same products throughout keeps the estate consistent.

Mastic sealing in Worcester Park, done properly

On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. If you’re dealing with movement joints with sealant missing and water getting in round frames after rain, we can put it right, whatever the surface. Whoever orders the work in Worcester Park, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

London’s ULEZ covers every borough, and parking and loading rules vary street by street. For block-wide work, a place to park and store materials saves time on every visit.

A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or email us and we’ll come back to it.

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Failed window or door frames, which need a window contractor
  • Materials that need asbestos testing before work
  • Leaks from above rather than through a joint

If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Joints and surfaces we work on

  • Communal entrances and stairwells
  • Balcony and threshold joints
  • Shopfronts below residential blocks
  • Communal kitchens and washrooms
  • Window and door perimeters on blocks
  • External wall and movement joints

What sets the cost

We price every job individually. The main factors are:

  • Whether old sealant has to be cut out first
  • Which sealant the job calls for
  • Travel to remote or island sites
  • Induction, permit and paperwork requirements

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Asbestos survey details if the building is older
  • Anything awkward about access or site hours
  • Your programme or deadline
  • The site address and postcode

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or email a schedule or drawings.

Your questions answered

Can work in a care setting near Worcester Park go ahead while residents are there?

Yes. We work around residents’ routines, a room or two at a time. Noise and disruption are kept to a minimum.

Does your area include sites such as Beverley Trading Estate, near Worcester Park?

Yes. We cover Worcester Park and the area around it, including industrial estates, business parks and retail parks such as Beverley Trading Estate. Photos and a short description are enough for a first look.

How do you reach windows on upper floors?

Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place and we will confirm the approach in the quote.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Do you cover Worcester Park?

Yes. We take on work across Worcester Park, and the same phone number covers every area.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Do you do block-wide mastic programmes?

Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

Our process

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a job in Worcester Park, access comes first. Send the building rules and access times with your enquiry.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. A fixed quote follows, split by block or building if that suits you.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Before we start on site

  • Agree which areas must stay open
  • Have the specification and drawings to hand
  • Clear stock, furniture or equipment away from the joints

Advice

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Mastic sealing in Worcester Park: the local picture

In London, mastic work on a block goes through the managing agent or landlord, with notice to residents. We fit the programme to your notice periods. Worcester Park has six care or nursing homes no more than 2 miles away. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents.

Site managers at schools like Cuddington Community Primary School can fit frame mastic into the summer works. Student blocks close to universities like Kingston University (2.8 miles north-west of Worcester Park) are easiest to work on between tenancies.

What we’re called out for in Worcester Park

We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and it tears.

Clients usually get in touch after noticing one or more of the following:

  • The same joint failures repeated across a portfolio
  • Old repairs sealed over failed mastic
  • Damp patches beside frames
  • Complaints coming in block by block

For owners of several units at places like Beverley Trading Estate, 1.6 miles to the north-east of Worcester Park, one programme can deal with frame and external mastic across the lot.
