Proper preparation
A common cause of sealant failure is poor preparation. A good contractor removes old sealant completely, cleans the joint and primes or backs it where the system requires. Skipping this step saves time on the day but costs money later when the joint fails.
Correct product selection
Commercial work uses different products for different joints. Silicone, polyurethane, polysulphide, hybrid and acrylic systems each have their place. The contractor should select the right sealant for the substrate, joint size, movement and exposure, based on manufacturer guidance and any project specification.
Site discipline and documentation
On commercial sites, turning up on time, working safely and providing risk assessments and method statements matters. Insurance should be in place and available on request. Programme coordination and working around other trades are also part of the job.
Real project evidence
Ask for examples of similar work. A contractor should be able to point to completed commercial projects, such as stadiums, offices, hotels or healthcare premises. Look for clear photos, project scope and the type of work they actually carried out.
How to compare quotes
A commercial quote should be clear on the scope, the areas to be sealed, the access method, the programme and what is included in the price. The cheapest quote is not always the best if it misses preparation, access or the right product. Make sure the quote matches the work described.
