Job Description

1930s detached brick and rendered detached home

Work started in August 2020, and was to be done in stages

Job Description

The clients contacted Retrofit Projects following a recommendation from an interior designer, who was concerned about dampness in the home and heavy salts resulting in perished plaster to the living room.

Certain remedial works were required before any internal decoration could be considered.

A detailed survey was carried out at the property, and it was found that the external walls had an issue with possible rubble in the base of the walls and staining to chimney breasts from defective flues and chimney stacks.

The clients wanted to improve the energy efficiency of certain bedrooms and external walls, and at the same time resolve the damp and plaster issues.

The property needed significant up-grading and modernisation to make it warmer and more comfortable for the future.

The survey and report provided by Retrofit Projects allowed the client to fully appreciate the extent of the work required, and the expected costs and duration of the project.

Jobs Completed

SOLUTIONS

The work was in two parts, first floor insulation ( EWI ) to outside walls, and ground floor remedial works including new additional airbricks and cavity cleaning, followed by specialist remedial work and replastering.

Stage 1 - Insulation system applied to bedroom walls

External walls that were to receive the internal wall insulation system developed by Retrofit Projects and THIAS ( UK ) were first stripped of all lining paper.
Skirting boards were removed.
All walls were sterilised and cleaned with an approved mould treatment product.
Treated timber battens were fixed to the walls to be insulated at predetermined centres.
Very high-performance phenolic insulation boards were fixed to the battens.
The boards were further prepared to take the second stage of the insulation system.
When dry, the thermal boards were lined with a 2-layer thermal insulation system and left to dry.
The walls were decorated, and skirting boards painted to complete the work.
The EWI system installed would dramatically reduce heat loss, and have a much warmer surface, reducing the risk of mould and condensation in the future.

Stage 2 - Ground floor remedial works

Cavity cleaning and removal of debris at the base of the walls.
New air bricks to provide additional ventilation to the ground floor timber joists and floorboards.
Timber treatments, and floorboard replacement.
Replastering using a renovating plaster system, and specialist treatments to stop both dampness and salts returning in the future.

All work undertaken is covered by a full guarantee on both labour and materials.
