Construction mastic in Sacombe Green, done properly
On refurbishments, the mastic package typically includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. If you’re dealing with new external sealant already peeling away and internal caulk splitting as the building dries out, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Sacombe Green it comes down to the same thing: the right product in a properly prepared joint.
Sites around smaller places like Sacombe Green can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What sealant work can’t fix
Some faults sit outside our scope, and we say so rather than covering them up:
- Designing joint widths or choosing the specification (that sits with the designer)
- Frame gaps too wide for sealant, which the installer needs to correct
- Approving fire stopping as compliant
If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer.
Joints and surfaces we work on

What the job involves on each surface
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used and hygienic or food-safe grades wherever food contact is possible.
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps. Record requirements are agreed with the quote.

Questions we are asked in Sacombe Green
Do you cover business parks and estates near Sacombe Green, such as Thundridge Business Park?
Yes. Our area takes in Sacombe Green and its surroundings, with estates and business parks such as Thundridge Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Is Sacombe Green too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
What does a mastic package typically include?
It depends on the specification, but frames, sanitary, kitchens, caulk where specified and snagging are typical.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Phasing around occupants
- The total length or number of joints
- How much existing material needs removing
- Travel to remote or island sites
A quote for mastic packages depends on quantities, condition and access. Call for a quote.
Before you send an enquiry
However big the job, the same details help:
- Any dates the work must fit around
- How the joints are reached, and at what height
- The product your specification calls for
- Asbestos survey details if the building is older
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Maintenance after handover
For the best life from the joints:
- Stick to the specified sealant rather than a generic substitute
- Check frame gaps are within the sealant’s range before sealing
- Don’t schedule sealing before decorators and flooring are done
- Plan external elevations with the weather in mind
The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault.
External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work.
Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If others near Sacombe Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Send your site hours and access windows
- Let building users know which areas are affected
- Explain the parking and delivery arrangements
