Conservatory, Fascia & Window Cleaning

uPVC fascias, soffits, conservatory and windows often suffer from the build up of algae, dirt and staining. DSC Exterior Cleaning provides expert, timely and affordable cleaning of conservatories, fascias, soffits and windows for home owners in Devon and Somerset.

 

 





Using a reach-and-wash, soft washing or pure water system we clean all your uPVC or painted timber frames and get them gleaming again. Our conservatory, fascia and window cleaning service operates in Exeter, Barnstaple, Tiverton, Cullompton, Exmouth and Taunton and the surrounding regions.

What is uPVC Cleaning?

uPVC cleaning is the professional process of removing dirt, algae, stains and environmental build-up from plastic exterior surfaces around your home. While uPVC is often marketed as a maintenance-free material, it still requires periodic cleaning to keep it looking its best and functioning properly. Over time, exposure to rain, pollution, algae growth and general grime can leave surfaces dull, discoloured and unsightly.

Similarly, painted timber window frames, conservatories, soffits and fascias suffer from the same exposure and build up of dirt and algae. In some cases, where painted timber has not been cleaned and maintained, dirt and algae are contributing factor in flaking and damaged paintwork that in turn can be the causes of rot and expensive repairs. We recommend keeping clean your painted timber surfaces to avoid costly repairs. Our cleaning method is gentle and thorough and suitable for all exterior surfaces.

Fascia Cleaning

Fascias are the horizontal boards that run along the edge of your roofline, supporting the bottom row of roof tiles and holding the guttering in place. Because they are constantly exposed to the elements, fascias can quickly accumulate dirt, algae, and pollution stains.

Professional fascia cleaning removes this build-up and restores the bright appearance of the roofline. Our pure water or soft washing process ensures the surface is cleaned safely without scratching or damaging the plastic material.

Regular cleaning can also prevent organic build-up that may contribute to blocked gutters or staining spreading down walls.

  • Restores the appearance of roofline fascias

  • Removes algae, dirt and pollution staining

  • Helps prevent build-up affecting gutters and drainage


Soffit Cleaning

Soffits are the boards located underneath the fascia and roof overhang. These often contain ventilation holes that allow air to circulate through the roof space, helping prevent moisture and condensation issues in the loft.

Because soffits are positioned underneath the roofline, they often collect cobwebs, dirt and airborne grime that gradually dull their appearance. Professional soffit cleaning ensures these surfaces are restored while keeping ventilation points clear and functioning properly.

Our ground-based cleaning methods allow us to safely clean soffits without unnecessary ladder use, reducing the risk of damage while delivering excellent results.

  • Removes dirt, cobwebs and grime from soffits

  • Helps maintain proper ventilation in roof spaces

  • Safe ground-based cleaning reduces risk of damage


Conservatory Cleaning

Conservatories are a fantastic addition to any home, providing bright living spaces that connect the indoors with the garden. However, their large glass and uPVC surfaces can quickly accumulate algae, moss, leaf debris and general grime.

Professional conservatory cleaning restores the appearance of frames, glass panels and roof sections, allowing more natural light to enter the space. Our cleaning process is gentle but highly effective, removing organic growth and stains while protecting seals and plastic components.

Regular cleaning also helps maintain the longevity of conservatory materials, preventing long-term staining or degradation.

  • Cleans frames, roofs and glass panels

  • Removes algae, moss and environmental build-up

  • Helps maintain light levels and conservatory appearance

Cleaning Methods

We use specialist techniques designed to safely clean delicate plastic surfaces without damaging them. At DSC External Cleaning, we use modern equipment, soft washing technology and purified water systems to achieve excellent results.

Unlike harsh pressure washing, our cleaning methods focus on controlled water flow and agitation using a soft pole-mounted brush. This ensures dirt, algae and stains are effectively removed while protecting the integrity of the surface.


Soft Wash or Pure Water Cleaning?

Soft washing uses dilute biocides which kill algae and restore the uPVC or painted timber to a shining clean surface. This method also provides a degree of ongoing protection against organic growth. Soft washing is what we commonly use and recommend for all uPVC, conservatory, fascia and soffit cleaning.

  • Ideal for uPVC or painted timber frames
  • Kills and protects again organic growth
  • Leaves surfaces white and gleaming

Pure water cleaning, on the other hand, is used primarily for window cleaning as it uses highly filtered water that has been purified to remove minerals and impurities. This water naturally attracts dirt particles, allowing them to be lifted away from the glass surface without leaving residue or streaks behind.

Because pure water dries naturally without mineral deposits, it provides a spotless finish that keeps surfaces looking cleaner for longer.

  • Uses purified water for a spotless finish

  • Leaves no streaks or residue behind

  • No harsh chemicals are use


Reach & Wash System

Reach and wash systems use telescopic poles that allow technicians to clean high or difficult-to-access areas safely from the ground. This method eliminates the need for ladders in many situations and reduces the risk of accidental damage.

The system combines purified water with specialist brushes to gently remove dirt and organic growth from fascias, conservatories and windows.

  • Ground-based cleaning for increased safety

  • Reaches high areas without ladders

  • Effective for rooflines, windows and conservatories


uPVC Algae Removal

Algae and organic growth are common problems on exterior plastic surfaces, particularly in shaded or damp areas. Our soft washing process includes the use of professional biocidal treatments that eliminate algae at the source.

This treatment does more than simply remove visible stains—it helps prevent regrowth, keeping surfaces cleaner for longer.

  • Removes algae, mould and organic growth

  • Biocidal treatment prevents rapid regrowth

  • Long-lasting cleaning results
