Our Services Explained

Extensions provide a great way to gain extra space in your home – and are usually less disruptive and more affordable than moving house.  

Planned well, any extension will add real value to a typical home – it could even recover the full cost of the project! 

Whether you want to cash in, or enjoy the benefit yourself, we offer a modern, practical and trustworthy service. 

Using our in-house team, we cover all the trades you need, and manage the project from end-to-end – from ground works to final decoration. 

We always aim to exceed expectations, and are committed 100% to customer satisfaction.


If you plan an extension, check if you need planning permission first. This is the responsibility of the property owner, and current guidance can be found at mygov.scot. 

If your property is within a conservation area, there may be additional restrictions for you to consider. 

If the planned work does need planning permission, this should be secured before work begins. 

Find out how to apply by visiting your local council website.


We help you make the right choices, to reflect your budget, space and requirements. 


Converting an unused basement could increase the value of your property substantially.

Add a bedroom, with or without an en-suite bathroom. Opt for a home office. Or simply add storage space. We can even install a new kitchen. 

The potential is almost limitless – subject to the engineering. (A basement conversion always has to allow for the structural loading of your property.)

With assistance from our sister company, Alliance Preservation Scotland, we can ‘tank’ your basement to ensure that it remains water-tight. 


If your home has sufficient loft space, then this conversion is a most cost-effective way to add an extra room, and increase the value of your home. 

The key thing is to make sure that the style of conversion is right. For example, if you can’t access the entire roof space, then a dormer loft conversion is a good option.


If, like 90% of homeowners in the UK, the last thing that ever enters your garage is a car, why not turn this underused floor space into a usable room?


When you hire a company to carry out your building renovations, you want to be able to enjoy the highest quality of workmanship, and that is precisely what we provide. 

With Alliance, you know you are choosing an experienced company to deliver a quality result on your refurbishment or renovation. 

We also minimise any inconvenience –working fast, but always maintaining the very highest standards. 

Our in-house team of trained, highly competent tradesmen, each excel at their own individual responsibilities, and cover all aspects of building services:

  • Plumbing
  • Electrics
  • Plastering
  • Joinery
  • Painting and decorating
  • Roofing
  • Tiling

Kitchens / bathrooms

If you are only going to improve one room, make it the kitchen. It is the hub of family life.

This is a long-term investment, and designers recommend installing equipment that won’t look out of date in five years. Budgets might seem daunting, but spend in proportion to the overall value of your home, to get a return on your investment. If that falls within the UK average – £215,847 in 2017 – there’s no benefit in splashing out £20,000 on a new kitchen. 

Typically, new kitchens add about 4.5% to the value of your home; so budget wisely. That way, you’ll enjoy a new kitchen, and potentially get your money back when it comes to selling. That’s a tasty result!

Modern bathrooms also appeal to buyers.


Our team has a proven track record delivering commercial, industrial and residential roofing projects. No matter what system you are looking for, we can make your roof an asset.

Alliance are accredited installers of KÖSTER PO Single-Ply Roofing Membrane. This system comes with a 25-year guarantee: it is environmentally friendly and plasticiser free.

It is also resistant to UV rays and high mechanical stress and its crack bridging ability withstands temperature-induced movement.

The thermoplastic characteristics of the KÖSTER membrane create an inseparable, durable and homogeneous bond. 

It is perfectly suited to quick and easy application and is either loose-laid with ballast, fixed mechanically, or fully bonded. In each case, the seams are hot air welded, allowing safe application even in problem areas. 

Our roofing team can also help with:

  • Renewal of rainwater guttering
  • Re-pointing of chimney stacks, parapet walls etc
  • Re-roofing, either with the original or new materials
  • Flat roofs a speciality

Flood damage

If you’ve had the nightmare experience of a flood, we can get you back into your premises fast. 

Unlike many building services companies, we stock our own pumps and dehumidifiers, meaning we can get straight down to helping you. Our in-house team can fully refurbish your premises, working as a pre-approved supplier for all trades on many insurers’ panels.


This needn’t cost a great deal, but the impression of a newly decorated interior will lift your spirts, and boost the valuation of your property. (Or at least prevent a tired or out-of-date look pulling it down.) Don’t forget the exterior paintwork either, for that perfect first impression.


All commercial or residential projects can be delivered; including traditional plasterwork, roughcasting and even specialist plasterwork on historic buildings.

Rest assured, until the final finishing touch is applied, every client receives our utmost individual attention. 

Our attention to detail and focus on customer service is always the same. Throughout each project, you work with a single foreman or project manager. 

We deliver the highest quality of workmanship, time after time: a fact reinforced by our on-going work with many professional clients, including housing associations, architects and letting agents.
