What Hungerford’s businesses ask us to seal

Hungerford lies roughly 62 miles out from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Firms with branches across the South East can use one contractor for every site. Several hotels sit less than 2 miles from Hungerford. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, and the work can be phased so the rest of the hotel keeps trading.

Premises within reach of Hungerford station, under half a mile to the north-east of Hungerford, often have busy frontages where joints are seen by everyone passing. In hotels such as Three Swans Hotel, under half a mile north-east of Hungerford, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Hungerford is about 8 miles west of Newbury, in West Berkshire. We cover Hungerford, with the same fixed quotes and 12-month guarantee as everywhere else. Our West Berkshire coverage takes in 140 places, large and small. Our Reading page has more on work in that area, about 23 miles away.

We take on sealant joints across the RG17 postcode area, whatever the building. For a building on High Street, Lancaster Square and Station Road or nearby, send details and we’ll quote for sealant joints. You will find Hungerford on or near the A4 and A338, so getting applicators and materials to site is simple. We also cover Eddington (1 mile north-east), Upper Eddington (1 mile north), Leverton (1 mile north), Chilton Foliat (2 miles north-west) and Woodlands St Mary (4 miles north) for sealant joints. Further afield, our area takes in Newbury (8 miles east), Thatcham (11 miles east), Speenhamland (8 miles east), Lambourn (7 miles north), Shaw (9 miles east) and Wash Common (8 miles east). Among the larger centres in West Berkshire is Hungerford, and we take on sealant joints for its commercial and public buildings.

Commercial sealant contractors for commercial buildings in Hungerford

We have applied sealant on commercial sites for over 20 years, and the documents buyers ask for are ready: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. The enquiries we see most involve wall and floor joints that have lost their seal and smeared sealant across finishes from a rushed job, across washrooms and tea points, movement joints in walls and floors and window and door perimeters. A single leaking joint is often how a building in Hungerford first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In an occupied building in Hungerford, the job is planned so areas stay in use: we agree the order with you and hand back each area with its cure time.

Places like Hungerford tend to have a handful of commercial buildings: a local shop, a pub or restaurant, a surgery, a school and the odd office or workshop. They’re not big jobs one by one, but their joints need the same preparation as anywhere.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

After the work

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Keep barriers up until the new sealant has cured
  • Deal with small splits before they become leaks
  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Keep abrasive pads and scrapers off resealed joints

We stand behind the workmanship with a 12-month guarantee. Keep the handover details with your O&M or maintenance records.

Occupiers often notice failing sealant before the facilities team does. Replacing it on a planned cycle keeps complaints down.

On site: what to expect

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For a site in Hungerford, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.

  1. We start with the evidence: photos, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Point out any areas we must not close
  • Move anything stored against the joints

Questions we are asked in Hungerford

Do you cover business parks and estates near Hungerford, such as Hungerford Trading Estate?

Yes. Our area takes in Hungerford and its surroundings, with estates and business parks such as Hungerford Trading Estate included. To start, just give us a call on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Is Hungerford too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can you take on work for an FM or managing agent?

Yes. You can send details through our quote form, and tell us what site paperwork you need.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Is it OK to apply fresh sealant over existing beads?

The old bead is stripped out first. After that come cleaning, primer where needed, backing and the new sealant.

Common problems we fix in Hungerford

Outside, sunlight and rain wear sealant down year after year. Sunny elevations dry the surface out and exposed ones take driving rain, so beads chalk, stiffen and lose their stretch. A hardened bead can’t follow the building any more.

It’s worth sending us details if you spot any of the following:

  • Damp patches where an external joint has failed
  • Frame sealant that has cracked, shrunk or pulled away
  • Black mould through washroom sealant that won’t clean off
  • Movement joints packed with grit and debris

A business with units at Hungerford Trading Estate and Station Yard Business Park needn’t use two contractors for its sealant.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • How the joint faces will be prepared and primed
  • The terms of the workmanship guarantee
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

Building owners, agents and FMs in Hungerford

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

What the job involves on each surface

Facade and cladding joints

Facade sealant failures can be hard to spot from the ground. Close-up photos or a site visit tell us what’s needed, with colours confirmed for the product chosen.

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. We will recommend the right filler or sealant for the traffic and movement.
