Expert Window Repairs and Maintenance in Essex and London

Here at E & C Construction Ltd, we take on refurbishment projects to restore sash and casement windows but also anything that is made of wood like doors, roof fascia’s and soffits. The epoxy system that we use gives the ultimate advantage when it comes to long-term maintenance of public, commercial and domestic properties. It provides substantial cost benefits whilst providing a sustainable alternative to replacement which is even more beneficial in conservative areas that do not allow the replacements of windows or doors. Paint durability is significantly improved and at the same time it offers significant protection of future rotting decay. Below are pictures of the stages that each window goes through, showing you from start to finish the process of restoring windows and doors.

The repair care system is made using a compound which is one of the new generations of high-performance materials to repair any type of joinery wood whether its inside or outside. It is suitable for making any type of resin repair between 5-50mm thickness. It has high adhesive qualities and holds its shape without slumping or sagging even before it has cured.

Stage 1

The first stage is identifying decayed and rotten wood by checking thoroughly every part of the window. As you can see from the images above, this is a sash window which has been destroyed by the outside forces. You would probably think that we cannot make this window look anything like the original, but our team of trained and qualified personnel are experienced experts who can re-model any type of wooden window, or door.

Stage 2

In the second stage of the entire process, we start to remove any rotting and decaying wood by using a multi tool. The white and healthy wood that is exposed means that all rotten wood has been removed. All exposed and healthy wood is then brushed with a rot hardener. The hardener is a penetrating 2-part clear compound primer that binds the repair and bonds with the epoxy repair compound. It is crucial that this step is taken to ensure a strong bond between the new and existing wood. In the meantime, while the epoxy repair compound is setting in and drying, the team uses a wide range of power and hand tools to shape and mould each individual piece of new wood to match the existing that has been cut out. The last picture in the slideshow is an example of this.

Characteristics of the hardener

  • Low viscosity
  • Penetrates more quickly and more deeply into the wood
  • Strengthens the fibres of the wood
  • Easy brush application
  • Simple and clean to mix

Stage 3

The third and last stage includes coating all the new wooden pieces with a weather shield preservative primer which penetrates wood to seal and preserve against water damage, decay and blue stain fungi. This is the reason the new pieces appear as a green colour and not their original colour when bare. It provides 8 years weathering durability which is a big thumbs up if we are talking about wooden windows and doors. We coat them before we fit them back on the window or door because all sides and ends must be coated to ensure humidity does not have a starting point for decay. After this our teams finally use the epoxy repair compound to put everything back together and make the window look and function as if nothing was wrong with it before. Once the windows are painted with undercoat and gloss, you will not be able to notice that the window was worked on in the first place.

To recap our progress, our teams up until now have done the following:

  1. Identified rotten wood
  2. Removed it with the multi tools
  3. Coated the bare existing wood with the rot hardener
  4. Prepared the new wooden pieces with various power and hand tools to exactly match the size and dimensions of the existing rotten pieces
  5. Coated all the new pieces with the weather shield preservative primer to help ensure it does not decay anytime soon
  6. Fit everything back together on the window with the epoxy repair compound
