About our mastic sealing in Thrupp

For blocks and buildings in Thrupp and across Oxfordshire, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. If you are dealing with communal area joints that look neglected and estate-wide sealant that is simply worn out, we can help, whatever the surface. Searching for sealant specialists in Thrupp? We’ve been sealing commercial buildings since 2005.

In and around smaller places like Thrupp, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Thrupp: questions and answers

Can you work at a site such as Oxford Spires Business Park, by Thrupp?

Yes, sites like Oxford Spires Business Park are within our area, along with the rest of Thrupp. Send details of the unit and the work through our quote form for a quick quote.

Will you take on a block within reach of Oxford Parkway station?

Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.

Can you plan resealing across several buildings?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

How do you reach windows on upper floors?

Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

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.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Water coming in from the roof or rainwater goods
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)

Not sure which it is? You can give us a call on 01277 525 020 or email us and we will tell you honestly.

Joints and surfaces we work on

  • Communal entrances and stairwells
  • Window and door perimeters on blocks
  • Balcony and threshold joints
  • External wall and movement joints
  • Shopfronts below residential blocks
  • Communal kitchens and washrooms

From enquiry to sign-off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. For a building around Thrupp, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Tell staff and tenants when we will be in
  • For older buildings, check the asbestos register before work

Advice

Maintenance after handover

To get the most from the new sealant:

  • Share your contractor requirements early
  • Avoid piecemeal callouts where you can
  • Track which buildings were done and when
  • Start inspections with the most exposed faces

Keep records of when each building was resealed. That makes future programmes easier to plan and gives you a history.

Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.

What affects the price in Thrupp

A fixed quote reflects the actual work. It allows for:

  • Distance, for remote addresses
  • The product specified
  • Access and working height
  • Phasing around occupants

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Details that help us quote

However big the job, these details speed things up:

  • When you need the work done
  • How the joints are reached, and at what height
  • The site address and postcode
  • Asbestos survey details if the building is older

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, ring 01277 525 020 or email drawings and photos.

Owners, agents and contractors

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

For owners and agents in Thrupp

Thrupp is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Thrupp is about 57 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.

Owners of student blocks near University Field Station, 3.9 miles south of Thrupp, can schedule frame and external mastic for the summer vacation. Schools and community buildings such as The Marlborough Church of England School need frame and external mastic kept sound like any building. Blocks of flats and mixed-use buildings often cluster around stations such as Oxford Parkway station (to the south-east of Thrupp) and their window and balcony mastic tends to age at the same rate across a building.

Thrupp is about 7 miles north-west of Oxford, in Oxfordshire. Across the OX5 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Oxfordshire coverage takes in 423 places, from busy centres to rural villages. For work in that direction, see our Oxford page.

We cover the OX5 postcode districts. We also cover Shipton-on-Cherwell (1 mile north), Begbroke (1 mile south-west), Bunkers Hill (1 mile north), Woodstock (2 miles west) and Bladon (2 miles west) for mastic joints. Bigger towns within reach include Oxford (7 miles south-east), Bicester (8 miles north-east), Abingdon-on-Thames (11 miles south), Witney (9 miles south-west), Carterton (13 miles west) and Headington Quarry (7 miles south-east).
