Why it’s worth doing now in Streatham Park

A torn seal left alone typically gets worse. Grit and water fill the gap and the material either side breaks up. Resealing early keeps the work to sealant. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Why clients in Streatham Park choose us

  • Colours confirmed for the specified product
  • One contact handling all your sites
  • Old sealant cut out, never sealed over
  • A range of standard colours, depending on the product

Quoting for work in Streatham Park

A fixed quote reflects the actual work. It takes account of:

  • Induction, permit and paperwork requirements
  • The total length or number of joints
  • Specialist products, such as fire-rated or hygienic sealants
  • Distance, for remote addresses

No two sites price the same: 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

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

  • When you need the work done
  • The product your specification calls for
  • Approximate linear metres or a joint schedule
  • The asbestos register, for older buildings

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to speak to us on 01277 525 020 or send photos by email.

Different surfaces, different methods

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.

Your questions answered

Do you work in London buildings with loading restrictions?

Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.

Can you work on a hospital site such as Springfield University Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

What if the joint edges are damaged?

A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we’ll say so when we quote.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

What will the job cost?

Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or use the quote form with a description of the work.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Commercial clients in Streatham Park

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

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. In Streatham Park, 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 look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.
