RANGE REVIEW: WEATHERPROOFING W


eatherproofing is a high-margin, basket-building category that thrives on seasonal urgency


(autumn/winter), impulse add-ons at the till, and simple “I-can-do- that” projects. Here’s a practical rundown of what to promote, why it matters, and which proven products to put on the shelf.


The core jobs most customers want to tackle


1. Stop the draughts at doors and windows


The fastest wins happen around moving parts – letterplates, sashes, and door bottoms. Carry a good- better-best ladder of self-adhesive seals so staff can size the gap and upsell. Stormguard’s EPDM profiles are retail staples: ‘E’ for small gaps       EPDM’s springy memory means fewer call-backs than basic foam and a longer service life – perfect for repeat-worthy word-of-mouth. Don’t forget the letterbox: draught-sealing letterplates with internal brush seals (e.g., Yale’s Yaleseal range) solve a problem customers can feel every windy day and make an easy add-on at checkout.


2. Add a ‘second skin’ to cold glazing


Secondary glazing film is the seasonal hero: quick sale, big perceived benefit. Stock branded kits in multiple sizes and price points (Stormguard or Exitex). These clear shrink-fit films create an insulating air layer on single-glazed or leaky frames; they’re especially effective in rentals and period homes. Position them as a weekend job that pays back immediately.


3. Seal leaks where water wins Roofs, flashings, gutters, and joints are repeat offenders. A well-curated shelf of all-weather sealants and tapes lets customers fix issues between downpours. Everbuild’s Black Jack line remains a go-to:      is a fibre-reinforced, brush-on bitumen that resists wash-off almost immediately – great for emergency repairs. Pair it with self-adhesive Black Jack Flashing Tape for quick, lead-look sealing around upstands and joints.

WEATHERPROOFING THAT SELLS: WHAT DIY RETAILERS SHOULD STOCK AND HOW TO MERCHANDISE IT


Energy prices may ebb and flow, but one constant remains: UK homeowners want warmer, drier, less draughty homes without calling in a contractor. That’s your sweet spot.


even in wet conditions – reducing returns when the weather won’t     adhesive is another popular option for customers who want one cartridge that bonds and seals across dissimilar materials.


4. Keep masonry breathable and dry Persistent rain + porous brickwork = damp, heat loss and flaking paint. Breathable creams and water repellents are easy to demo in-store and deliver visible beading that sells the story. Safeguard Europe’s Stormdry Masonry Protection Cream lines pores with a water- repellent silicone matrix, shedding rain while allowing the wall to     remains a household name for clear masonry waterproofing on brick and stone, handy for customers who want a brand they recognise.


5. Insulate the ‘forgotten’ pipes and taps Frozen external taps and uninsulated pipes are classic “oh no” moments after the first frost. Stock pipe lagging     mm) with clear bay signage so customers can self-select. Climaflex polyethylene sleeves are widely used and review well at retail. Add a stack of insulated outside tap covers near the plumbing aisle and at the seasonal endcap for impulse protection buys. 6. Weatherproof – and refresh – exterior finishes A tidy, sealed envelope keeps heat in and water out. Exterior masonry paint with weather protection (e.g.,    Masonry) offers quick wins and repeat sales on rollers, filler, and masking. Train staff to ask about prep (cleaning, stabilising solution) to grow basket size.


Newer/standout products worth ranging this season • Stormguard Seasonal Double Glazing Film – Big seasonal volume driver; easy install with a hairdryer; sell in multiple sizes. Merchandising tip: open sample on a ‘cold window’ display to show the clarity and beading. • Exitex Secondary Glazing Film Kits – Position as a lower-cost alternative to permanent secondary glazing; cross-sell with tape and a glass cleaning kit for best adhesion.


• Everbuild Black Jack 905 All- Weather Roof Coating + Flashing Tape – A simple, confidence- building roof repair duo customers understand; create a “leak fix” bay with brushes, gloves, and cleaner. • Everbuild Weather Mate – Exterior gap filler/sealant that can be applied in wet weather; perfect “I need to fix it today” solution. • CT1 Hybrid Sealant/Adhesive – One-cartridge answer for bonding and sealing—reduces decision fatigue at the fixture.
