About our commercial sealant contractors in Forest Hill

Pricing a commercial reseal is a short process. Send photos, drawings or a schedule of the joints through our quote form; you can also call 01277 525 020 or send details through our quote form with the details. If the joints need seeing in person, a site visit comes first, followed by a fixed quote rather than an estimate that drifts. We work on floor and threshold joints, kitchen worktops and splashbacks and external facade joints, and what we are called in for most is black mould through washroom sealant that won’t clean off and window and door perimeter joints that have cracked open. Whoever orders the work in Forest Hill, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

On a typical commercial building in Forest Hill, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

Commercial sealant work around smaller places like Forest Hill tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

FAQs: Forest Hill

Can you supply sealant in our brand colour for a site in Forest Hill?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Available colours for the product are confirmed with the quote.

Can you work at a site such as Littleworth Industrial Estate, by Forest Hill?

Yes, sites like Littleworth Industrial Estate are within our area, along with the rest of Forest Hill. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Could the old sealant in an older building contain asbestos?

Some older mastics did contain asbestos. So we check the register first and stop work on anything suspect until it’s tested.

Will the building have to shut during the work?

It’s mostly about sequence: areas are phased, access windows agreed and enough washrooms or entrances left in use. Let us know what can’t close and we will work around it.

How many days will you need on site?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

Is failed sealant stripped out, or sealed over?

Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip, and the faces are brought back to sound, dry material before resealing.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

Commercial premises in Forest Hill

The 3 miles around Forest Hill take in at least three named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal. The South East is one of the drier parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.

On estates like Littleworth Industrial Estate (1.4 miles south of Forest Hill), the office and welfare end of each unit has its own sealant to maintain.

Common problems we fix in Forest Hill

The wrong sealant in the wrong place is a common cause of early failure. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade will all fail early. BS 6213 gives guidance on choosing construction sealants.

Clients normally get in touch after noticing something like this:

  • Layers of sealant, all of them failing
  • Frame sealant that has cracked, shrunk or pulled away
  • Untidy joints in a reception, shop floor or lobby
  • Shrunken sealant along kitchen worktops and splashbacks

Occupiers with premises at both Littleworth Industrial Estate and Shotover Trading Estate could have the sealant at each handled under one quote.

Before you book anyone

  • Who will actually carry out the work
  • Will RAMS and insurance details be available?
  • Health and safety accreditation such as CHAS
  • The named product and why it was chosen

How to choose a sealant contractor

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Leave it or put it right?

A cheaper quote sometimes means the old bead stays in. Sealing over looks tidy at handover, then lifts once the joint starts moving. Our prices always include removal of the failed bead and full joint preparation, which is where the lasting value is. For buildings around smaller places like Forest Hill, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

A quote for sealant joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

What affects the price in Forest Hill

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Distance, for remote addresses
  • Site requirements such as inductions and permits
  • Access and working height
  • Specialist products, such as fire-rated or hygienic sealants

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

Before you send an enquiry

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

  • When you need the work done
  • Specification clauses that apply
  • Whether an asbestos survey exists
  • What the building is and how it’s used

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, phone 01277 525 020 or email the details over.

Our process

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Forest Hill, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First, details come to us: photos, drawings or a schedule of the areas, or we arrange a site visit.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Before we start on site

  • Move anything stored against the joints
  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
