When something else is needed

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
  • Rework caused by others damaging completed areas
  • Designing joint widths or choosing the specification (that sits with the designer)

If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think.

Joints and surfaces we work on

  • Floor and skirting junctions
  • Sanitary and kitchen joints
  • Brick and block movement joints
  • Internal decorators’ caulk
  • Window and door perimeters
  • Cladding and panel joints

How we handle construction mastic in Horne

The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. If you have frame gaps too wide for sealant alone and inconsistent sealant finishes from plot to plot, we can help. Searching for sealant specialists in Horne? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Around smaller places like Horne, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Contractors’ notes for Horne

Rainfall across the South East, Horne included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Central London is about 22 miles from Horne. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

Extensions at sites like East Surrey Hospital (to the north-west of Horne) usually sit beside working departments, and the mastic follows strict access rules. Units on estates such as Hays Bridge Business Park, 0.6 miles to the east of Horne, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Horne is about 4 miles east of Horley, in Surrey. Across the RH6 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Surrey coverage takes in 379 places. We also cover London, around 22 miles from Horne.

No. Places such as Horne are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Are you insured?

Can you clear a mastic snag list before handover?

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or send details through our quote form. Include photographs or drawings if you have them.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Our process

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 typically takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. Smaller jobs around Horne can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We walk the site or review drawings to understand the package.
  2. A fixed quote sets out scope, products and phasing.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Any frame gaps or issues outside our scope are flagged to the site team.
  6. Final snagging is completed and the 12-month guarantee applies.

Preparing the site

  • Share your working hours and any access restrictions
  • Move anything stored against the joints
  • Let us know about inductions and permits

Get a fixed quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or send photos by email.

Advice

After the work

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

  • Flag uneven or tapered frame gaps early
  • Ask for joint and product checks before the package is urgent
  • Bring the mastic contractor in after the last trades are through
  • Protect sealed areas from following trades

Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.

Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out, and avoids a rush.

Why it’s worth doing now in Horne

Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal. We’ll say so if a frame itself is the problem. Converted and older buildings near places like Horne tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

What the job involves on each surface

External facade and movement joints

Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it.

Window and door perimeters

Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. We follow what’s specified, and colour-matched products can be used where the frame is on show.
