Common questions from Skinners Green clients

Will you take on work at estates like Newbury Retail Park, close to Skinners Green?

Yes. We cover Skinners Green and the area around it, including industrial estates, business parks and retail parks such as Newbury Retail Park. Photos and a short description are enough for a first look.

Is Skinners Green too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Can one contractor look after sealant on all our buildings?

Yes. Give us the sites and the scope at each, and we will put together a fixed quote and a sensible order of work.

What guarantee do you give on resealing?

Our workmanship is guaranteed for 12 months. We’re fully insured for public liability as well.

How is commercial sealant work priced?

Send photographs, drawings or a list of locations. If a visit is needed we’ll book one, and a fixed quote follows.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Commercial sealant contractors in Skinners Green

Failed sealant isn’t always the whole story. Water at a window perimeter might be coming from the frame, the cill or the wall behind while a movement joint that keeps tearing may simply be too narrow for the job. We look before we quote and tell you plainly if sealant won’t solve it. Site teams most often ask us about weathered facade sealant that no longer flexes and damp patches where an external joint has failed, across external facade joints, kitchen worktops and splashbacks and movement joints in walls and floors. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Skinners Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

On a typical commercial building in Skinners Green, 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.

Work in smaller places such as Skinners Green tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Leave it or put it right?

Leaving a failed joint rarely saves money. Once water gets behind the seal, finishes and ceilings underneath are next, and the bill then involves other trades. Resealing while only the sealant has failed keeps the job small. Around Skinners Green, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Why us?

  • Sealing commercial buildings since 2005
  • Work to your specification and the manufacturer’s guidance
  • 12-month guarantee on workmanship
  • Matching to RAL references, product permitting

Cost factors for sealant joints

What shapes the price:

  • Working within restricted access windows
  • Site requirements such as inductions and permits
  • Backing rod, priming and other preparation
  • The total length or number of joints

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Sending details for a quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • The asbestos register, for older buildings
  • Rough lengths or quantities, or drawings if you have them
  • Anything awkward about access or site hours
  • The product your specification calls for

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Cracking that needs a structural engineer to look at it
  • A failed roof covering or waterproofing membrane

If you are not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Joints and surfaces we work on

  • Floor and threshold joints
  • Movement joints in walls and floors
  • Kitchen worktops and splashbacks
  • External facade joints
  • Washrooms and tea points
  • Window and door perimeters

On site: what to expect

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For work around Skinners Green, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

Getting the site ready

  • Let building users know which areas are affected
  • Flag any permit to work we’ll need
  • Clear stock, furniture or equipment away from the joints

Quotes

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or send details through our quote form.

Signs you need commercial sealant contractors in Skinners Green

Resealing over the top is a false economy we come across often. New silicone has nothing to key into. By the time it shows, there can be two or three layers to cut out.

These are often picked up first by site or facilities staff:

  • Layers of sealant, all of them failing
  • Mouldy silicone around WCs, urinals and vanity tops
  • Weathered facade sealant that no longer flexes
  • Gaps behind commercial kitchen worktops and sinks

A business with units at Newbury Retail Park and Parkway Shopping Centre needn’t use two contractors for its sealant.

Questions to ask before you book

  • How joint depth will be controlled
  • Their pre-qualification and accreditations
  • Proof of insurance
  • What site paperwork they can supply

What Skinners Green’s businesses ask us to seal

The area within 2 miles of Skinners Green holds plenty of hotels. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet. Skinners Green is in the South East, one of the UK’s drier regions. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.

Offices and shops close to stations such as Newbury station (1.6 miles north-east of Skinners Green) tend to be busy all day, so sealant work is planned around opening hours. Units at retail parks like Newbury Retail Park, 1.7 miles to the east of Skinners Green, change hands and get refitted, with new joints at every frontage.

Skinners Green is about 2 miles south-west of Newbury, in West Berkshire. Across the RG14 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Looking after the joints

A few simple habits keep the new joints working:

  • Keep barriers up until the new sealant has cured
  • Look at the sealant around anything that has been moved or replaced
  • Make sure ventilation in wet areas is switched on and working
  • Put external and wet-area joints on a regular inspection round

Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them and the joint gets left open. If that happens, give us a call on 01277 525 020 or email us and we will price putting it right.

Each spell of wet weather pushes more water through an open joint. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.
