5 Step Replacement upvc Cladding Method

Often one of the most striking external areas on a property is the Timber External Cladding area found on the front wall or around the dormer windows of your home. It is also the area that requires the most maintenance. External ladding generally comes in large expanses, ongoing maintenance is essential to ensure that the boards stay watertight. UPVC Shiplap Cladding, particularly around the side cheeks of dormers requires Specialist access equipment for decorating the area safely

Step 1 – Access

Installing an area such as cladding normally involves scaffolding as no weight from ladders or leaning platforms are to be applied to the Upvc.

Step 2 – Setting up access and removal of timbers

Shiplap external cladding is removed from the battens beneath from the bottom up. Care is taken on ripping the slats out as the felt beneath can easily be pierced. Battens are normally fixed firmly onto the breezeblock and are very rarely showing signs of rot. Remaining nails that have not come away with the slats are removed so that the area beneath is level and flush to fix the new uPVC cladding to.

Step 3 – Repairing felt and battens

Repairing felt that has been torn away is easily done by overlapping and sliding under new pieces of felt to the areas pierced. In the case that insulation is either deteriorated or not present – more can always be applied at this stage, effectively filling the spaces between the battens beneath the felt.

Step 4 – Setting up Shiplap cladding

Starter trims that hold the first length of the replacement uPVc cladding in place are screwed firmly through the leadwork and into the battens. Then, the first trims and lengths of cladding are installed using at least a 1 meter level across the entire length of the dormer on each side.

Step 5 – Installing Shiplap cladding

Each length of plastic cladding slots into the one beneath so that the area is installed from the bottom up. Installing the uPVC or embossed cladding this way makes it impossible for running water to get between the slats as the grooves insert to a depth of 30mm from the next. Trims are then fixed either side of windows (where applicable) to ensure a watertight seal. Corner trims are added for finishing off before the whole area is cleaned thoroughly.

A solid fix on shiplap or embossed cladding replacement is essential - once the render or hanging tile has been removed fix 9mm plywood as a backing board ( unless this brings you out past the verge overhang or a window cill ) before installing the upvc cladding with 40mm stainless steel pins
