What Exterior Cladding Actually Does for Your Home

Exterior cladding is a layer of material fixed to the outside of your walls. It acts as a weather barrier, reduces heat loss through exposed walls, and can transform the look of a property that has seen better days. Common systems include uPVC or composite boards, timber boarding, and through-coloured render systems applied over insulation boards.

Cladding is not just cosmetic. When render cracks, timber rots, or original boards pull away from the substrate, rain can track behind the surface and cause damage that is expensive to fix. Getting the right system fitted properly is the point at which future problems are either prevented or stored up.

Choosing a Cladding Contractor in Cottenham - What to Look For

This is the part most homeowners underestimate. Finding someone who can fit cladding is not difficult. Finding someone who will specify the right system, prepare the substrate properly and stand behind the finished job is harder. Here is what to focus on when you are talking to contractors.

Ask These Questions Before You Agree to Anything

• What are you fixing the cladding to, and how will you check it is sound? Cladding fixed to a damp, crumbling or structurally weak substrate will fail early. A contractor should inspect the wall first, not just measure it for a price.
• Will you address any underlying damp or render failure before you clad over it? Cladding over a wet wall traps moisture and can cause serious long-term damage. Ask whether the existing surface will be treated, dried, or stripped back before installation begins.
• What system are you recommending and why? A good contractor should be able to explain why one product suits your building better than another - not just say "we use this board" without a reason. Different wall types, exposure levels and building ages call for different systems.
• How will you handle window and door reveals, soffits, and junctions? The edges and corners of a cladding job are where it either performs well or fails. Detailing around openings, at eaves level, and where cladding meets other materials needs care. Ask to see examples of finished work, not just flat-panel photographs.
• Is the material you are recommending suitable for my property type? Some boards are appropriate for a 1980s brick extension but look wrong on an older property. Some render systems are not compatible with certain original finishes. Ask whether planning permission or permitted development rules apply before you commit.
• What does your price include? Make sure you understand whether scaffolding is included, whether disposal of old material is covered, and what happens if additional preparation work is found to be needed once the existing surface is stripped back.
• Can you show me completed jobs locally? Ask whether there are finished jobs you can see in person, ideally nearby villages or in the Ely area, so you can judge the quality of their detailing work for yourself.

Red Flags to Watch For

Any contractor who quotes a price on a doorstep without inspecting the wall should be treated with caution. Exterior cladding costs vary significantly depending on what is underneath, what system is used, and how much preparation is required - a number given without a proper look is unlikely to be accurate.

Be wary of contractors who push a single product regardless of your building type. Unskilled fitting of the wrong system is one of the most common causes of premature cladding failure. A contractor who listens to what you want, inspects the substrate, and then recommends a system with clear reasons is a better sign than one who arrives with a fixed specification.

Price is not the only measure of value. A cheaper installation that requires remedial work in three years costs more overall than a properly priced job done correctly. Ask for a written breakdown of what is included so you are comparing like for like.

Materials and Systems - What the Options Mean in Practice

uPVC and composite cladding boards are low-maintenance once fitted and resist rot and moisture well. They suit a wide range of property types and come in a broad range of profiles and colours. Timber boarding gives a more traditional appearance but requires periodic treatment to prevent moisture penetration and should be specified with proper breather membrane behind it.

Render-over-insulation systems, sometimes called external wall insulation or EWI, bond insulation boards to the existing wall and apply a thin render coat over the top. These are more involved to install and require careful detailing, but they improve thermal performance noticeably. They need a contractor who understands the system fully, not just someone who has used the boards before.

For a straightforward re-clad on a standard home in and around Cottenham, uPVC or composite board systems typically cost in the range of £80-£130 per square metre fully installed, depending on the profile, the condition of the substrate, and the complexity of the elevations. Render-over-insulation systems are generally higher. These are indicative figures - your actual cost depends on a proper site assessment.

What a Good Installation Looks Like

Proper cladding work starts with the wall, not the boards. The existing surface should be assessed for damp, structural soundness and adhesion. Any failed render, loose sections or damp patches should be dealt with before anything is fixed over the top. Fixings should be the right type for the substrate - not universal screws hammered in without consideration of what is behind.

Breather membranes or ventilation gaps, where required by the system, should be installed correctly. Trims, flashings and sealants at every junction - around windows, at eaves, at corners - should be neat, weather-tight and suited to the material. Any cladding job that finishes with gaps, misaligned boards or poorly formed corners will allow water ingress at those points first.
