Facade sealing in Dorchester, done properly
Managing agents and owners in Dorchester ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. If you have failed sealant on precast panel joints and previous reseals run over old sealant, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Dorchester is the same: the right product in a properly prepared joint.
Around smaller places like Dorchester, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

What affects the price in Dorchester
Quotes vary with the job. It mainly depends on:
- Travel to remote or island sites
- Which sealant the job calls for
- Whether the work must be split into stages
- Induction, permit and paperwork requirements
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.
Details that help us quote
There’s no need for a formal survey. These details are enough to start:
- Access details, including height
- Whether an asbestos survey exists
- The postcode of the building
- Rough lengths or quantities, or drawings if you have them
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or use the quote form to discuss it first.
Facade sealing in Dorchester: the local picture
A 2-mile radius around Dorchester takes in several hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.
Work at a hotel such as The White Hart Hotel (to the south-west of Dorchester) tends to be programmed around bookings, mastic included. New wings at hospitals like Littlemore Hospital, 5.6 miles to the north-west of Dorchester, bring long runs of window and panel joints to seal.
Dorchester is about 4 miles north-east of Didcot, in Oxfordshire. Any commercial site in Dorchester is covered, whether it’s a single job or part of a planned programme. Dorchester is one of 423 places we cover in Oxfordshire for facade joints. Oxford is covered too, around 8 miles from Dorchester.

Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
How a job runs
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Rural sites near Dorchester may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Getting the site ready
- Tell us your opening times and when work is allowed
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000

For managing agents and facilities managers
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Different surfaces, different methods
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface, often a low-modulus silicone or hybrid.
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod, primed where the maker specifies.
Signs you need facade sealing in Dorchester
Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building, then it splits or peels.
Any of the following is a good reason to get the joints checked over:
- Cold air coming in at window perimeters
- Cladding panel joints that have opened up
- Facade joints cracked through the middle
- Unsightly perimeter sealant on a visible elevation
School extensions, at buildings such as Dorchester St Birinus Church of England School, typically run to the summer holidays, mastic included.

Your questions answered
Is Dorchester off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Would you work within a site like Littlemore Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
How many days will you need on site?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Can you find out why a window is leaking?
Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can you work in cold or wet weather?
Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things throughout the job.
Do you use silicone for external joints?
The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.
