Facade sealing for Hyde farm estate sites

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

Facade sealing in Hyde farm estate

We don’t install glazing systems or replace glass. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. If you have new sealant peeling off old mastic and hard, chalky sealant that no longer flexes, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Hyde farm estate, preparation and product choice get the time they need.

A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Building owners, agents and FMs in Hyde farm estate

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

What sets the cost

Your fixed quote is built from the real scope. It allows for:

  • Specialist products, such as fire-rated or hygienic sealants
  • Whether the work must be split into stages
  • Any access equipment needed
  • The total length or number of joints

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What we need to price the job

Good information means a firmer quote. Helpful details to send:

  • The site address and postcode
  • What the building is and how it’s used
  • Drawings or a marked-up plan, if available
  • When you need the work done

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

Questions we are asked in Hyde farm estate

Can you cope with the access rules in a London building?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough

Can you work at a site such as Zennor Road Industrial Estate, by Hyde farm estate?

Yes, sites like Zennor Road Industrial Estate are within our area, along with the rest of Hyde farm estate. Photos and a short description are enough for a first look.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

Can you work on upper floors?

That varies with the building and the access on offer. Share what access exists or is planned when you send details, and we will plan the work with you.

Do you use silicone for external joints?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Check the asbestos register before old mastic is disturbed
  • Plan facade sealing alongside redecoration
  • Never let anyone seal over old sealant
  • Add perimeter sealant to planned maintenance checks

Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and cuts time on site.

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. In Hyde farm estate, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Share your working hours and any access restrictions
  • Tell us what induction or permit system the site runs
  • Make sure the joints can be reached

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email the details over.

The ULEZ covers the whole of Greater London, Hyde farm estate included, so site vehicles need to meet its standards or pay the daily charge. Delivery slots and scarce storage shape how and when the mastic goes in. The area within 2 miles of Hyde farm estate holds a good number of hotels.
