About commercial sealant contractors in RG28
Having a single contact for all your sites makes sealant far simpler to manage. Single jobs, multi-site packages and planned programmes all come to us, run the same way on every site: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. For sites in RG28, the quickest start is to give us a call on 01277 525 020 or send photos by email with a list of addresses. Site teams most often ask us about weathered facade sealant that no longer flexes and leaks that seem to come through a sealant line, on kitchen worktops and splashbacks, window and door perimeters and floor and threshold joints.
Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use.
- We start with the evidence: photos, drawings or a look on site.
- You get a fixed quote covering removal, preparation and the new sealant.
- Sequence, access and working times are settled before the first joint is touched.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- Completed areas are signed off with you under our 12-month guarantee.
How we quote
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
Why appoint us
- Colour options checked against the specified product
- One number for every site we cover
- Coloured sealants to suit the setting, where available
- Failed material removed, not covered up
Getting 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’ll fill any gaps with a visit.

Commercial sealant contractors across RG28: the area picture
The commercial stock in RG28 mixes older town-centre buildings with newer offices and units, in places such as Whitchurch, Freefolk and Laverstoke and beyond. Each building needs the right product for its surfaces, from stone and brick to coated aluminium and laminate.
Around the motorway corridors of the South East, business parks and industrial estates are common, and RG28 is part of the area we cover.
Whitchurch: Premises within reach of Whitchurch (Hampshire) station, 0.5 miles to the north of Whitchurch, often have busy frontages where joints are seen by everyone passing. On estates like Ardglen Industrial Estate (under half a mile north-west of Whitchurch), the office and welfare end of each unit has its own sealant to maintain.
What happens if it’s left?
Some managers wait for a fit-out before touching the mastic. That’s reasonable for internal joints that are just tired-looking, but a joint letting water in now keeps doing damage until the refurb arrives. We can seal the urgent joints now and leave the rest for the programme.
What your quote should include
- Can the work be phased to keep areas open?
- Whether old or failed sealant will be cut out, not overlaid
- Who will actually carry out the work
- Do they follow the manufacturer’s priming guidance?
Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Work for main contractors and building owners
Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.
What sealant work can’t fix
Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:
- Misted, cracked or failed glazing units (a glazier’s job)
- Leaks from pipework, wastes or valves (that’s plumbing)
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
Common problems we fix in RG28
A good share of the joints we inspect were topped up instead of being renewed. Fresh sealant won’t stick to the old bead underneath so it soon peels and traps moisture against the joint. By the time it shows, there can be two or three layers to cut out.
Common reasons buildings call us in:
- Layers of sealant, all of them failing
- Black mould through washroom sealant that won’t clean off
- Smeared sealant across finishes from a rushed job
- Water staining near frames, panels or ceilings
Questions about RG28
How is commercial sealant work priced?
The main factors are metres of joint, removal, access, the product and how many phases there are. For a fixed quote, send details through our quote form.
How many days will you need on site?
That varies with the scale of the job, but the work usually takes part of a day on a small job and longer where several buildings or phases are involved. For bigger or phased jobs, we’ll set out a timescale with the quote.
Does weather matter for sealant work?
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.
Does commercial sealant work come with a guarantee?
It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Is RG28 in your area?
Yes. RG28 falls within our area, and you can give us a call on 01277 525 020 or email a schedule or drawings to get started.
