What Newton Longville’s businesses ask us to seal

Newton Longville is about 44 miles from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings. The South East is one of the drier parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.

Offices and shops close to stations such as Bletchley station, 2.1 miles to the north-east of Newton Longville, tend to be busy all day, so sealant work is planned around opening hours.

Newton Longville is about 2 miles south-west of Bletchley, in Buckinghamshire. Any commercial site in Newton Longville is covered, whether it’s a single job or part of a planned programme. We work across 308 places in Buckinghamshire. Oxford is covered too, some 25 miles away.

Anyone looking for commercial sealant contractors in MK17 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Among the streets we cover are Manor Road, Dickens Close and Cobb Hall Road, and sites on any of them can send details for a fixed quote. If your building is just outside Newton Longville, we cover Newton Leys (1 mile east), Salden (2 miles south-west), Drayton Parslow (2 miles south), Bletchley (2 miles north-east) and Tattenhoe (2 miles north-west). A short drive away, we cover Aylesbury (11 miles south), Buckingham (9 miles west), Elmhurst (10 miles south), Southcourt (12 miles south), Haydon Hill (11 miles south) and Turnfurlong (11 miles south).

Commercial sealant contractors for commercial buildings in Newton Longville

Most of the buildings we seal stay open while we are there. Work is scheduled around the site hours and access windows you give us; phased work can also be planned so areas stay in use. That applies whether the building is an office, a shop, a hotel, a college or a care home. The enquiries we see most involve untidy joints in a reception, shop floor or lobby and weathered facade sealant that no longer flexes, across movement joints in walls and floors, floor and threshold joints and external facade joints. A specialist sealant contractor works differently from a general builder: in Newton Longville, that means joint design, primers and backing rod as standard.

Quotes for commercial sealant in Newton Longville can come from photographs and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.

A job in a smaller place like Newton Longville is typically a single building. 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.

How the job changes by surface

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, phasing the rooms so not every toilet is closed at once.

Shop fronts and retail fit-outs

Retail work usually has to fit around trading. Tell us your trading hours and access windows and we will plan around them.

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking anything from part of a day on a short run of joints to several weeks on a large phased package. Rural sites near Newton Longville may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  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. 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. Completed areas are signed off with you under our 12-month guarantee.

What we need from you

  • Tell us what induction or permit system the site runs
  • Point out any areas we must not close
  • Confirm the product named in the specification

Getting a fixed quote

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or send photos by email.

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • A dripping trap, valve or pipe behind a fitting
  • Broken glass or blown double-glazed units
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)

If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

What we seal

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

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Why deal with it now?

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. In many cases the element is fine and only the seal around it has given up. Resealing typically costs far less than renewal, and we will say so if the frame or fitting is life-expired. Around Newton Longville, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Common problems we fix in Newton Longville

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.

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

  • Mouldy silicone around WCs, urinals and vanity tops
  • Earlier reseals applied straight onto the failed bead
  • Messy, uneven beads from earlier work that let the building down
  • Frame mastic that has hardened and come away from the wall

Retail sites such as North Furzton Shopping Centre (2.4 miles north of Newton Longville) are typical of where shop-fit joints, frontages and staff areas need neat, colour-matched sealant.

What to look for in a quote

  • What the guarantee covers, and for how long
  • Proof of insurance
  • How the existing material will be dealt with
  • Health and safety accreditation such as CHAS

Questions about Newton Longville

Is Newton Longville too far out for you?

No. Places such as Newton Longville are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you cover business parks and estates near Newton Longville, such as North Furzton Shopping Centre?

Yes. Estates, retail parks and business parks around Newton Longville, North Furzton Shopping Centre among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

How do we get a quote?

The main factors are metres of joint, removal, access, the product and how many phases there are. To get a fixed price, send details through our quote form, or phone or email us.

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.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

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

Yes. We quote, schedule and report back in the way that suits your process, with a 12-month guarantee on the workmanship.

What about asbestos in old mastic?

It can, on some older buildings. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.
