Mastic sealing near Eastcote

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What sets the cost

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Specialist products, such as fire-rated or hygienic sealants
  • Removal of failed or old sealant
  • The total length or number of joints
  • The size and state of each joint

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Details that help us quote

Good information means a firmer quote. When you get in touch, include:

  • The site address and postcode
  • Clear photographs of the problem areas
  • The asbestos register, for older buildings
  • Anything awkward about access or site hours

To get a fixed quote, ring 01277 525 020 or email us with the site address and an outline of the work. Our quote form is another easy route.

Mastic sealing for commercial buildings in Eastcote

Owners and agents normally inherit a building’s mastic rather than choose it, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. If you have patchy repairs in mismatched sealant and worn sealant at communal door frames, we can put it right, whatever the surface. Most enquiries from Eastcote start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Across Greater London, Eastcote included, the ULEZ applies, and parking and loading rules differ from street to street. For block-wide work, a place to park and store materials saves time on every visit.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Start inspections with the most exposed faces
  • Keep bins and bikes away from communal door frames
  • Plan resealing building by building rather than complaint by complaint
  • Share the asbestos register when you send details

Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.

The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.

Eastcote: questions and answers

Do you work for managing agents with blocks near Headstone Lane station?

Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Will you take on work at estates like Braintree Road Industrial Estate, close to Eastcote?

Yes. Our area takes in Eastcote and its surroundings, with estates and business parks such as Braintree Road Industrial Estate included. A few photographs and the unit address let us price the work.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Will residents or tenants be disturbed?

Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.

What about access for upper-floor joints?

It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.

Do you do block-wide mastic programmes?

Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

What the job involves on each surface

Commercial and mixed-use buildings

Mixed-use buildings combine shops below with flats or offices above the programme has to suit everyone. Tell us your site hours and access windows and we’ll plan around them.

Tenement and older buildings

Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. Suspect material is tested before work continues.

Why deal with it now?

Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows and occupiers notice. Getting scaffold, permits or access booked in Eastcote takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Why us?

  • Colours confirmed for the specified product
  • One number for every site we cover
  • 12-month guarantee on workmanship
  • Products installed to the manufacturer’s instructions

How a job runs

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. All of Greater London is in the ULEZ, and kerbside space in Eastcote can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Old mastic is removed and the joint faces prepared.
  5. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

Getting the site ready

  • Have the specification and drawings to hand
  • Send your site hours and access windows
  • Let building users know which areas are affected
