Need mastic sealing in Silchester?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:

  • Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
  • Failed window or door frames, which need a window contractor
  • Misted or failed double-glazed units

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

What we seal

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

About our mastic sealing in Silchester

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. If you are dealing with damaged joints in communal entrances and corridors and a mix of products and colours from past repairs, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Silchester is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Owners and agents with buildings around smaller places such as Silchester tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Silchester are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Point out parking and an unloading spot
  • Let us know about inductions and permits

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Questions we’re asked in Silchester

Is Silchester too small for you to travel to?

No. Places such as Silchester are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Is Stacey Industrial Park, near Silchester, within your area?

Yes. We cover Silchester and the area around it, including industrial estates, business parks and retail parks such as Stacey Industrial Park. Send details of the unit and the work through our quote form for a quick quote.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

Do you work with property factors and landlords?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

How long do sealant joints last?

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 inspection is the best way to catch problems early.

Do you need mastic sealing in Silchester?

The edges of the material itself sometimes break away for instance where render or brick edges crumble. We’ll tell you if the joint edges need repairing before resealing.

Common reasons buildings call us in:

  • A mix of products and colours from past repairs
  • Movement joints with sealant missing
  • Window mastic that has split and shrunk
  • Water getting in round frames after rain

Buildings close to stations like Bramley (Hants) station (2.4 miles south-east of Silchester) are often flats over shops, with frame mastic to keep sound.

Before you book anyone

  • Whether their applicators hold CSCS cards
  • Which product they’ll use, and why it suits the joint
  • How the existing material will be dealt with
  • Their plan for phasing and protecting the area

Our contractor checklist

Mastic sealing around Silchester: what changes locally

Silchester sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first. Silchester lies roughly 45 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.

If you are responsible for a building such as Saint Luke's Church, frame and door mastic needs the same attention as any other property. If you own or manage units on a site such as Stacey Industrial Park, 1.2 miles west of Silchester, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Silchester is about 2 miles east of Tadley, in Hampshire. Our applicators travel to Silchester for work on mastic joints, handled exactly as we handle every other area. Silchester is one of 723 places we cover in Hampshire for mastic joints. There’s a separate page for Reading, about 8 miles away.

Anyone looking for mastic sealing in RG7 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Streets here include Little London Road, Romans Field and Dukes Ride. Just outside Silchester, we also work in Pamber Heath (1 mile north-west), Aldermaston Soke (1 mile north-west), Old Warren (2 miles north-west), Little London (2 miles south) and Pamber Green (2 miles south-west). A short drive away, we cover Basingstoke (6 miles south), Farnborough (15 miles east), Fleet (13 miles south-east), Alton (15 miles south), Yateley (12 miles east) and Hook (8 miles south-east).

Local landmarks in Silchester

We work on buildings around Padworth Common Local Nature Reserve. For rail, the closest station is Bramley (Hants) station, about 2.4 miles south-east of the centre. Well-known places in the area include Basingstoke and North Hampshire Hospital (5.1 miles south) and Calleva Museum (less than half a mile north-east). For a walk, there’s Hosehill Lake.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Why deal with it now?

Adding sealant to cyclical maintenance is an easy win. Waiting until leaks appear means working under pressure and less choice about when. One visit to deal with every failing joint makes more sense than several trips to a place like Silchester, rather than one at a time. Send photos of each area and we’ll quote for the lot.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
