The Pitfalls of Renovating your Home

Our previous blog post on adding an extension to your home proved popular. Extensions and renovations often go hand-in-hand. This post gives some additional advice so you can make an informed decision on any project you are planning for your home.


Don’t forget – if you’re planning to do a loft conversion, it’s essential that you do a thorough investigation of the existing foundations.  This is usually overlooked.  

Adding weight to poor foundations is a recipe for disaster.  Many Victorian houses are often built on old railway sleepers. After 130+ years, these are rotting or are already rotten. The rising water table in the Greenwich area adds to the problem.


Clients often underestimate the amount of work involved with renovations. Most decide to continue to live at the property while the renovations are carried out. But do you really want to live on a building site? Especially if you work from home.

There’s a lot of disruption during renovation work – dust, noise, loss of electrics and plumbing – including loss of use of your bathroom or kitchen. It can be stressful too. Imagine you’re on an important call, but the builder needs to carry on with his demolishing work, or drilling, or using a nail gun.  The delays caused by the presence of the client can increase the cost of the project by 20%.


The money clients think they will save by remaining in the house while major renovations are carried out is likely to be added to the final bill, as progress will be slowed and delayed by the client’s presence. 

Once work has started, there can be unexpected surprises. We might discover that a joist or beam needs replacing – something we couldn’t know until a floor or ceiling has been opened up. 

Clients sometimes worry about the loss of traditional features such as coving or ceiling roses. These are easily replaced by modern, lightweight versions which look just as good as the original in most cases but not always. 

We also find that many properties have sheets of 8 x 4 chipboard or 3 different layers of ply and self- levelling compounds covering the subfloor. These bows and move over time. You can’t lay new hardwood flooring if the subfloor is unsuitable. This leads to additional work and costs.  

Of course, there is no way of knowing if this work needs carrying out unless you lift the floor and find out. That’s why we recommend a thorough investigation before starting any renovation work, especially if the project involves removing internal load-bearing walls and adding new stud walls on the first floor or converting the loft. 


We recommend setting a target cost for a renovation project, with an additional allowance of 20%-30% for contingencies.

It’s always best to consult a professional builder for advice. One who can complete your project quickly and without hassle.
