Looking after the joints
After handover, a little attention goes a long way:
- Report cracked or peeling sealant early
- Put external and wet-area joints on a regular inspection round
- Make sure ventilation in wet areas is switched on and working
- Don’t let cleaning or traffic back on before the cure time is up
Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.
Once sealant fails in a movement joint, grit and debris get in. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.
Sealant specialists in Gallowstree Common
Mastic Doctor has been sealing joints for businesses and contractors since 2005: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. If your site needs RAMS, an insurance certificate or CSCS details, say so and we’ll confirm with the quote. Most enquiries involve wall and floor joints that have lost their seal and sanitary sealant that has gone black and patchy, on floor and threshold joints, movement joints in walls and floors and external facade joints. Whoever orders the work in Gallowstree Common, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Multi-site clients with buildings in and around Gallowstree Common can put several sites on one programme, so standards and paperwork match across every site.
A job in a smaller place like Gallowstree Common is usually a single building. We’ll want a full list and photographs 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.

Working on commercial sites near Gallowstree Common
Central London is about 39 miles from Gallowstree Common. Business parks and retail centres are common around the capital’s motorway corridors. Firms with branches across the South East can use one contractor for every site. Gallowstree Common sits in one of the drier corners of the country, the South East. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.
For tenants and agents on sites such as Vanalloys Business Park, 2.4 miles north of Gallowstree Common, office fit-outs, reception joints and window perimeters are the usual sealant work. For premises near Tilehurst station, which lies south of Gallowstree Common, footfall is part of the plan: work is phased so shops and offices keep trading.

Common questions from Gallowstree Common clients
Is Gallowstree Common too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can the sealant on our Gallowstree Common premises match the finishes?
Yes, we can normally get close to most finishes from the product’s colour range. The quote lists the colours the product is made in.
Does commercial sealant work come with a guarantee?
It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.
Do you work directly for building managers?
Yes. You send the details, we return a fixed quote, and the job is done and signed off.
Which site documents can you send us?
Let us know your requirements when you ask for a price, and the paperwork is confirmed with the quote. From you, we will need the asbestos information for older buildings and any site rules.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
What about asbestos in old mastic?
It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested. HSE guidance on asbestos is a useful reference.
What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Broken glass or blown double-glazed units
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Water from a services leak rather than a joint
If you are not sure, just call 01277 525 020 or email the details over and we will give you a straight answer before you book.

From enquiry to sign-off
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For work around Gallowstree Common, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First, details come to us: photographs, drawings or a schedule of the areas, or we arrange a site visit.
- We work out why the joints have failed and fix a quote for the agreed scope.
- Before anything is cut out, we agree access, timings and sequence.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- We fit backing to the right depth, prime where specified and lay the new bead.
- We walk the completed areas with you and sign them off under the 12-month guarantee.
Preparing the site
- Tell staff and tenants when we’ll be in

For managing agents and facilities managers
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. Keys, access and contacts can be agreed in advance.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Leave it or put it right?
Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. Converted and older buildings near places like Gallowstree Common tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
Why us?
- Constructionline member for supplier checks
- Coloured sealants to suit the setting, where available
- Over 20 years of commercial sealing
- Failed material removed, not covered up

What the job involves on each surface
Shop fronts and retail fit-outs
Retail work typically has to fit around trading. Tell us your trading hours and access windows and we will plan around them, working in sections where that helps.
Washrooms and toilets
Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, phasing the rooms so not every toilet is closed at once.
