The earlier you involve a weatherproofing specialist in a building penetrations project, the better. Ideally, this should happen during the design stage to give the project the best chance of developing a robust weatherproofing strategy. If that phase has passed, bringing in a specialist as soon as possible can help protect the building while reducing risks to the project’s budget and programme.
Why is early engagement with a weatherproofing specialist important?
Where pipes, cables and ductwork pass through the building envelope, careful detailing is necessary to maintain weather resistance and help prevent damage.
Without a weatherproofing specialist involved from the outset, responsibility can be passed from one trade to another until the work is almost complete. Resolving weatherproofing details at this stage may require remedial work to gain access to the penetration.
Involving Jones Weatherproofing early clarifies responsibilities and allows architects, façade designers, roofing contractors and M&E teams to address weatherproofing of both roof and vertical penetrations as part of the wider project design.
What are the benefits of involving a weatherproofing specialist early in a building penetrations project?
Getting the Jones Weatherproofing team involved early allows us to advise on service locations, weatherproofing details, structural considerations and how the work fits into the programme.
Benefits include:
- Expertise and experience – Weatherproofing specialists can identify issues early and recommend effective solutions.
Trade coordination – Including weatherproofing in the project programme from the start improves access and enables different trades to work together efficiently. - Clear responsibilities – Responsibility for weatherproofing often falls between trades. Early engagement minimises disputes.
Accurate, detailed drawings – Jones Weatherproofing can produce new drawings, review existing ones and advise on the proposed details. - Programme planning and fewer late-stage changes – Identifying potential challenges early can reduce the need for late changes. If plans do change, the weatherproofing team can respond efficiently.
- Less remedial work – If weatherproofing requirements are identified after services and other elements have been installed, parts of the installation may need to be removed or dismantled to provide access.
