Thinking about tackling a home improvement project? Whether it’s a new kitchen, an extra bedroom, or a full property refurbishment, the earlier you start planning, the smoother the process will be. Our Devon builders work with homeowners across Exeter and the wider Southwest on everything from small repairs to full-scale renovations, and getting booked in early means you avoid the scramble that comes with leaving it too late.
Our team of highly skilled and experienced Devon builders at Cowleyβs Building & Maintenance can complete a range of domestic and commercial building projects, including:
Not every job needs a big renovation plan. From door-hanging to flooring and everything in between, our general builders in Exeter handle the smaller jobs as carefully as the larger ones. As we’ve said before, there’s no job too big or too small for the team at Cowley’s.
Planning a new kitchen? Our kitchen fitters in Exeter handle every stage of the process, from design through to final installation. If you’re weighing up timelines, our guide on how long a kitchen installation takes is a good place to start, and our piece on quality kitchen installations covers what to expect from the finish.

Looking to update a tired bathroom or fit a new wetroom? Our bathroom fitters in Exeter can handle the full installation, from design and plumbing through to removal of the old suite. For smaller spaces, our tips for small bathrooms are worth a read before you start planning layouts.

A fresh coat of paint can transform a room, but getting a genuinely professional finish, especially across a full interior or exterior β is harder than it looks. Our painters and decorators in Exeter are on hand for jobs of any size.
Finding a reliable, cost-effective builder for a refurbishment project can be tricky – our guide on finding the best Devon builder for your home covers what to look out for. Whether it’s an internal refresh or an external overhaul, our property refurbishment team has the experience to see it through from start to finish, and can restore a building’s overall durability along the way.

Need more space rather than a full move? Our team can add property extensions to your home, whether that’s ground floor or upper floor. Since 2019, permitted development rules have made it easier for homeowners to extend without planning permission in many cases – worth checking our guide on whether you need planning permission for your extension before you start, and our roundup of the top 5 property extension types if you’re still deciding on the right approach.
Got a loft, garage or spare room that isn’t earning its keep? Our property conversions team has helped homeowners across Devon turn underused space into something genuinely functional β see our piece on everything you need to know about garage conversions or our loft conversion ideas and inspiration for a sense of what’s possible.

Building your dream home from the ground up? Our skilled team can see a new build through from inception to completion, liaising with your architect and project manager throughout.
Your outdoor space deserves as much attention as the inside of your home. From rendering and block paving to walling, decking and general garden transformations, our landscaping Exeter team can help – take a look at one of our recent garden landscaping projects in Heavitree to see the kind of transformation possible, or our simple ideas to improve your garden space if you’re still at the planning stage.
We’re passionate about helping every client feel safe and comfortable in their own home. Our disabled living adaptations service covers everything from bathroom and kitchen adaptations to wheelchair access, and we work closely with occupational therapists and housing adaptation officials throughout.
If you’re planning an office refit or need a suspended ceiling installed for a commercial or retail space, our residential team can still point you in the right direction – but you’ll find more relevant detail in our dedicated guide. Start your projects with Devon commercial builders, which covers office refits, suspended ceilings and commercial fit-outs in more depth.

Look for a builder with proven experience on projects similar in size and type to yours, proper insurance (public and employer’s liability as a minimum), and accreditations from recognised bodies. Ask to see previous work or speak to past clients, and always get a written, itemised quote before committing. Our own accreditations are listed on our Health & Safety/Accreditation page if you’d like to see ours.
As a general rule, the busier the season and the bigger the job, the further ahead you should book. Reputable local builders are often booked several weeks or months in advance, particularly heading into spring and summer when extensions, landscaping and renovation work peaks. If you have a specific timeframe in mind, it’s worth getting in touch early to secure your preferred slot.
It depends on the type and scale of work. Many extensions and conversions fall under permitted development rights and don’t need full planning permission, but this varies depending on your property type, location, and whether it’s listed or in a conservation area. Our guide on planning permission for extensions covers this in more detail, and we’re always happy to advise as part of an initial consultation.
Costs vary significantly depending on the scope, materials, and complexity of the project, so it’s difficult to give a meaningful figure without seeing the space and discussing your requirements. We provide free, no-obligation quotes for every project, so you’ll have a clear, itemised cost before deciding anything.
Most reputable builders work on a staged payment basis tied to project milestones, rather than requesting the full amount upfront. This protects both you and the builder, and keeps the project accountable to the agreed schedule. We’re happy to talk through payment structure as part of your quote.
