Commercial sealant contractors for businesses in Marshborough
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Why act early in Marshborough
Fixing joints complaint by complaint is a costly way to manage sealant. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We can help you prioritise, starting with the joints most likely to let water in. One visit to deal with every failing joint makes more sense than several trips to a place like Marshborough, rather than one at a time. Send photographs of each area and we will quote for the lot.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Sealant applicators in Marshborough
Sealant joints are easy to overlook until one lets water in, and on a working site that typically surfaces as a leak, a stain or a complaint from occupiers. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors with sites in Marshborough. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. If you have movement joints packed with grit and debris and frame mastic that has hardened and come away from the wall, we can put it right, whatever the surface. Whoever orders the work in Marshborough, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
If you look after more than one building near Marshborough, the work can be planned as one programme, with one quote format and one point of contact.
Rural business units near smaller places such as Marshborough are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.
A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, phone 01277 525 020 or use the quote form and we’ll arrange a return visit.

When to bring in a specialist
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Common questions from Marshborough clients
Must a hotel around Marshborough close while you work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we’ll plan around them.
Is a smaller place like Marshborough outside your area?
Not at all: smaller places are covered as well as 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.
Can you handle sealant work across several sites?
Yes. Give us the sites and the scope at each, and fixed prices follow, with a suggested sequence.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we will confirm them with the quote.
Will the building have to shut during the work?
It’s normal for us to work in occupied buildings. We agree the order of areas, protect what’s nearby and close off only the section we are sealing, until its cure time has passed.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Roof leaks that only look like a joint problem
- Old mastic that tests positive for asbestos
- Cracking that needs a structural engineer to look at it
If in doubt, call 01277 525 020 or email the details over and we’ll say what we think before you book.
What we seal
- Kitchen worktops and splashbacks
- Movement joints in walls and floors
- Window and door perimeters
- External facade joints
- Floor and threshold joints
- Washrooms and tea points
Different surfaces, different methods
Facade and cladding joints
On a facade, a failed joint is often only visible close up. Photos from a closer viewpoint help us price, and we’ll confirm the colours available for the specified product.
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. Replacement is the fix: strip, clean, dry and reseal, room by room if that suits the building.
From enquiry to sign-off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Marshborough may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- Send details through our quote form, or ask for a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- A suitable product for each joint goes in at the right depth and is tooled.
- We check the work with you, and the 12-month guarantee starts.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions
- Warn occupants and staff about the work

When to call us in Marshborough
A split down the middle of the bead tells a different story. Typically the movement was too much for the sealant chosen because the bead was too thin, the joint over-stretched or the movement class wrong. Replacing it like for like rarely holds.
Any of the following is a good reason to get the joints checked over:
- Earlier reseals applied straight onto the failed bead
- Expansion joints with the sealant torn out
- Damp patches where an external joint has failed
- Sanitary sealant that has gone black and patchy
For a hotel such as The Lion Hotel, 1.2 miles north-west of Marshborough, the colour of a joint at the bar or the bath matters to the look of the room.

What Marshborough’s businesses ask us to seal
Marshborough is in the South East, one of the UK’s drier regions. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. Marshborough has a number of hotels close by, all within 2 miles. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes; work is planned so the hotel keeps trading.
