Sealant applicators in Upton

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before old sealant is disturbed, because the duty to manage asbestos sits with the dutyholder. Anything suspect is left alone until it has been tested. We work on movement joints in walls and floors, washrooms and tea points and floor and threshold joints, and what we’re called in for most is messy, uneven beads from earlier work that let the building down and leaks that seem to come through a sealant line. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Upton, preparation and product choice get the time they need.

We price commercial jobs in Upton from photographs, drawings or a site visit, with the scope listed so everyone knows what’s included.

Work in smaller places such as Upton tends to come one building at a time: a pub kitchen, a hall, a small office. We’ll want a full list and photos first, so the right products come on the day and nothing waits for a second trip.

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.

Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Leave it or put it right?

Some managers wait for a fit-out before touching the mastic. That’s reasonable for internal joints that are just tired-looking, but external and wet-area joints that already leak shouldn’t wait. We can seal the urgent joints now and leave the rest for the programme. Around Upton, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote when you’re ready.

Different surfaces, different methods

Fire-rated seals where specified

Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. The design and sign-off of fire stopping belong to the designer and building control; we install what’s specified.

Facade and cladding joints

Facade joints move every day as panels warm and cool. The product has to suit the movement, and the depth has to be controlled with backing. We confirm the access in place before we quote.

Sealant on show in Upton’s commercial buildings

Upton lies roughly 50 miles out from central London. This part of the South East is dense with business parks and out-of-town offices. Firms with branches across the South East can use one contractor for every site. Upton has three care or nursing homes no more than 2 miles away. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean.

If you look after units at a retail site such as Market Place Shopping Centre, 2.1 miles to the north-east of Upton, shopfront perimeters and shop-fit joints are where a matched colour shows. Refits at hotels like The Kingswell Hotel, 1.3 miles to the north-west of Upton, bring joints at vanity tops, bars and reception desks that guests see every day. A business with units at Market Place Shopping Centre and Trident Business Park needn’t use two contractors for its sealant.

Upton is about 2 miles south of Didcot, in Oxfordshire. We send applicators to Upton for sealant joints. Across Oxfordshire, 423 places are covered, Upton among them. For work in that direction, see our Oxford page.

Postcode districts covered here: OX11. We cover commercial and managed buildings on High Street, London Road and Pound Lane and the roads nearby. Nearby places we also cover include West Hagbourne (1 mile north), Coscote (1 mile north), East Hagbourne (1 mile north-east), Blewbury (1 mile south-east) and Chilton (2 miles south-west) for sealant joints. Further afield, our area takes in Oxford (12 miles north), Abingdon-on-Thames (7 miles north), Wantage (7 miles west), Grove (7 miles west), Faringdon (15 miles west) and Benson (7 miles north-east).

What’s near Upton

Other landmarks nearby include Atlas Computer Laboratory (2.4 miles west) and Brightwell Castle (4.7 miles north-east). The countryside around Upton includes Churn Hill and Mowbray Fields.

Questions about Upton

Can the sealant on our Upton premises match the finishes?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.

Is Upton too far out for you?

No. Places such as Upton are covered as much as the big towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

How long does a job like this take?

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

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Is your work guaranteed?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

Our process

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Jobs in and around smaller places like Upton are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. First, details reach us through the quote form or a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Getting the site ready

  • Flag any permit to work we will need
  • Clear stock, furniture or equipment away from the joints
  • Send your site hours and access windows

Get a fixed quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Advice

What sealant work can’t fix

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

  • A dripping trap, valve or pipe behind a fitting
  • Structural cracks or movement the joints weren’t designed for
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)

If you’re not sure, just ring 01277 525 020 or use the quote form and we will give you a straight answer before you book.

What we seal

  • Movement joints in walls and floors
  • External facade joints

  • Window and door perimeters
  • Washrooms and tea points
