Mastic sealing for commercial buildings in Swallowfield
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on shopfronts below residential blocks, communal entrances and stairwells and balcony and threshold joints, and what we are called in for most is a mix of products and colours from past repairs and brittle perimeter mastic across a building. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Swallowfield, that means joint design, primers and backing rod as standard.
In and around smaller places like Swallowfield, 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.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Mastic sealing in Swallowfield: the local picture
Swallowfield is about 38 miles from central London. Within reach of London, blocks run by agents and associations are common around stations. Swallowfield sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Owners of student blocks near University of Reading - Whiteknights Campus (to the north of Swallowfield) can schedule frame and external mastic for the summer vacation. If your remit includes a building such as Lambs Lane Primary School, frame and door mastic can be programmed for the holidays. Property owners at sites such as Lambs Farm Business Park (0.7 miles north-west of Swallowfield) can have mastic renewed between lettings.
Swallowfield is about 5 miles south of Reading, in Wokingham. We cover commercial sites throughout Swallowfield. 42 places across Wokingham fall within our area, including Swallowfield.

On site: what to expect

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Advice
Should maintenance staff do it?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Questions we’re asked in Swallowfield
Is Swallowfield too small for you to travel to?
No. Places such as Swallowfield are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you quote for a block close to Mortimer station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
Do you work for managing agents and housing associations?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Joint width, depth and condition
- Quantities, in metres or numbers
- The site’s rules and procedures
- Removal of failed or old sealant
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Access details, including height
- Approximate linear metres or a joint schedule
- Asbestos survey details if the building is older
- Any specification or named product
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or use the quote form.
After the work
Problems stay small when the joints are checked regularly. Specifically:
- Make it easy for occupiers to report draughts
- Check sealant joints during planned building inspections
- Protect low-level joints in entrances
- Mention RAMS, insurance or CSCS requirements up front
If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, routine checks spot the next round of repairs.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.
Leave it or put it right?
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes and those cost far more to put right. Converted and older buildings near places like Swallowfield tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
