Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Our process
At the end of each section, 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. Jobs in and around smaller places like Fields End are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- Drawings, the sealant specification and your programme come to us for pricing.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- We seal each plot or floor as it’s released to us.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Let building users know which areas are affected
- Send any specification or drawings in advance

Construction mastic in Fields End
The specification and the programme set the job. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Backing, primer and depth follow what the sealant maker sets out. Most enquiries involve bath and shower joints scraped during the final clean and internal caulk splitting as the building dries out, across internal decorators’ caulk, brick and block movement joints and cladding and panel joints. A specialist sealant contractor works differently from a general builder: on jobs in Fields End, preparation and product choice get the time they need.
Sites around smaller places like Fields End 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 will quote to suit.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Signs you need construction mastic in Fields End
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly so we set the depth properly before sealing.
These are often picked up first by site or facilities staff:
- External joints sealed in damp or cold conditions that are now failing
- Bath and shower joints scraped during the final clean
- Frame gaps too wide for sealant alone
- Failed sealant in an existing building being refurbished
On a healthcare site such as Hemel Hempstead Hospital, 1.9 miles to the east of Fields End, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What your quote should include
- The named product and why it was chosen
- Their public liability cover
- How joint depth will be controlled
- Whether primer will be used where the manufacturer specifies it
Why act early in Fields End
When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference, especially externally. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Around Fields End, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.
Why us?
- 12 months’ guarantee on every job
- Failed material removed, not covered up
- Products installed to the manufacturer’s instructions
- Over 20 years of commercial sealing

Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Putting right a botched joint often costs more than sealing it well at the start, 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.
