How the job changes by surface
Window and door perimeters
The perimeter joint between a frame and the structure keeps rain out of the reveal. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.
Shop fronts and retail fit-outs
In retail, sealant is on show. Counters, display units, shopfront frames and floor trims all need a neat line. We’ll confirm the colours available for the specified product.
Sealant specialists in Downend
On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey. Anything suspect is left alone until it has been tested (removing asbestos-containing materials isn’t something we do). We work on movement joints in walls and floors, kitchen worktops and splashbacks and floor and threshold joints, and what we are called in for most is smeared sealant across finishes from a rushed job and leaks that seem to come through a sealant line. Looking for mastic applicators who cover Downend? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Quotes for commercial sealant in Downend can come from photographs and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.
Rural business units near smaller places such as Downend 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.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Shops, offices and hotels in and around Downend
Less than 3 miles from Downend there are at least three named estates and business parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints. Rainfall across the South East, Downend included, is lower than in many parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.
For premises near Smallbrook Junction station, which lies east of Downend, footfall is part of the plan: work is phased so shops and offices keep trading. If you have premises on more than one site, say at New Barn Industrial Park and Wootton Business Park, one contractor and one quote can cover both. A unit on an estate like New Barn Industrial Park, 1.5 miles south-west of Downend, normally has an office front, a trade counter and staff facilities with joints of their own.

Your questions answered
Can you match sealant colours for premises in Downend?

Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Will the building have to shut during the work?
Phased work can be planned so areas stay in use. Tell us your site hours and access windows and we’ll plan around them.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.
Cost factors for sealant joints
The price varies from site to site. Expect it to depend on:
- Induction, permit and paperwork requirements
- Location, for remote and island sites
- Whether old sealant has to be cut out first
- The product specified
Pricing sealant joints depends on quantities, condition and access. Ask us for a fixed quote.
What we need to price the job
Diagnosis starts before we arrive. Let us know:
- A wide shot and a close-up of the area
- Rough lengths or quantities, or drawings if you have them
- The postcode of the building
- Any specification or named product
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or send photos by email to discuss it first.
Our process
Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Downend are normally planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Where parts of the building must stay open, the work is phased.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
Preparing the site
- Let us know about inductions and permits
- Agree which areas must stay open
- Warn occupants and staff about the work
Ask for a quote
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
Looking after the joints
To get the most from the new sealant:
- Ask fit-out and M&E contractors to report any sealant they disturb
- Brief cleaning contractors to avoid scourers and blades on sealant
- Check sealant as part of routine building inspections
- Have extract fans checked so wet areas dry out
Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life; a mild cleaner is all most joints need.
A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.

Leave it or put it right?
Some low prices are low because nothing gets cut out. Sealing over looks tidy at handover, then lifts once the joint starts moving. Every quote we give includes full removal and preparation, because that’s what makes the new bead last. Around Downend, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
