One job, start to finish

Timber decking replacement, before and after.

Hot tub and wraparound deck · drag to compare

After: level Trex deck running from the house past the hot tub
Before: hot tub on an old timber platform beside a cracked concrete path
BeforeAfter
⟷
  1. The problem

    A cracked, uneven concrete path down the side of the house that the customer could barely walk out on, and a hot tub sitting on an old timber platform that was going soft.

  2. What Ellis did

    Took out the old timber and replaced the whole area with one continuous Trex deck. It wraps the house, sets the hot tub into the deck and opens onto a raised seating area with black railings.

  3. The result

    Level, slip-resistant decking from the back door to the hot tub, so the customer can get out and use the garden safely again. No more uneven concrete, no more rotting timber.

    The old boards come up and are cleared away before the new deck goes in.

    New frame where it's needed

    Hidden fixings, tidy finish, the site cleared and the deck walked through with you.

I recently had a composite decking fitted on my balcony by Ellis from Ellis Decks Ltd, and I couldn't be happier with the result. Ellis was excellent from start to finish, professional, reliable, and clearly takes great pride in his work. The workmanship is absolutely spot on, with great attention to detail and a high-quality finish. The decking has completely transformed the space and looks fantastic. I would highly recommend Ellis Decks Ltd to anyone looking for quality decking work. Thanks again, Ellis!

Ellis transformed our garden from a tired overgrown area into a fantastic outdoor living space that the family absolutely love. At the heart of the garden is an amazing decked area that was designed and built using high quality materials including the stunning Trex decking that comes with a peace of mind long warranty ranging from 25 to 50 years. Throughout the project Ellis’s communication, craftsmanship and professionalism were first class. Highly recommended and 5 Star rating.

We are absolutely delighted with our new decking! From start to finish, Ellis was a pleasure to work with and was happy to tweak the plans as the project progressed to make sure everything was exactly as we wanted. We've never met anyone quite as passionate about decking, which made us smile, but we also have nothing but respect for his craftsmanship and skill. Both Ellis and Liam were hardworking, easy-going, and maintained excellent communication throughout the entire process. We also really appreciated the extra help with the building of our pergola! Highly recommend.

We would like to thank Ellis for the advice, guidance & transformation of our dated & unsafe patio. Along with recommendations of Trex composite decking. He understood our brief and with his workforce executed it to the letter. His attention to detail was appreciated from start to finish including our choice of inlay of interconnected squares and all this was achieved within the agreed time & budget. Would highly recommend Ellis Decks, for the professional job which has been completed. We are looking forward to being able to enjoy our new decking in the near future. A big THANK YOU from S & D

Ellis was very professional from start to finish. He came up with very good ideas for the design. Extremely pleased with the finished deck and railing system.

I needed a new fence and a timber deck renewed at my property. I looked around a lot, found Ellis Decks, and through his photos I knew it was what I wanted. I had some samples of composite decking, but Ellis educated me about the differences between brands, and that Trex doesn't fade and has a proper guarantee - so although more expensive, it avoids the problems in the future. Ellis was punctual, friendly and went out of his way with his little worker Liam to make the dream a reality. Couldn't ask for a better outcome! Thank you Ellis Decks!!

Questions

Timber decking replacement FAQs.

Anything else, just ask. Ellis would rather answer a question than have you guess.

Dark raised Trex deck in the evening
How much does timber decking replacement cost?

It depends on the size, how high the deck sits and how many steps it has, whether your existing frame can be kept, which Trex range you choose and any extras like railings or lighting. Send Ellis a few photos of your current deck with rough measurements and he'll give you a ballpark before arranging a visit. No prices online, because no two decks are the same.

Do you take away the old timber deck?

Yes. The old boards come up and are taken away as part of the job, so you're not left with a pile of rotten timber in the garden.

Can you reuse my existing frame?

Sometimes. Ellis checks the frame on the site visit. If it's sound and spaced to suit Trex, it can stay. If it's soft, rotten or moving, it gets rebuilt, because new boards on a rotten frame won't last. You'll know which before the job is booked. Why the subframe matters.

How long does timber decking replacement take?

Most garden deck replacements take around 3 to 5 working days, including taking up the old deck. Bigger, raised or more complex decks take longer, and Ellis gives you a clear timeline before you book.

Is it worth replacing timber decking with composite?

If your boards are greying, soft or splitting, more treatment only buys a bit of time. Replacing your timber with Trex means no more staining, sanding or rot, backed by a 25 to 50 year warranty.

Is composite decking slippery?

Trex boards are designed with slip resistance in mind and grip better than weathered, algae-covered timber. A quick clean now and then keeps them that way, especially in shady, damp spots.

Do I need planning permission to replace a deck?

Replacing a deck like for like usually doesn't need it. If the new deck is bigger or sits more than 30cm off the ground it might, and listed buildings and conservation areas have extra rules. Ellis flags it at the design stage.

Can you change the layout while you’re replacing it?

Yes. You can keep the same size and shape, or use the replacement to add steps, lighting, built-in seating or a new layout. Ellis designs it in 3D first so you can see it before anything is built.

Can you replace decking around a hot tub?

Yes. Hot tub decks are one of the most common timber replacements, because the water speeds up rot. The deck can be built around the tub with access for servicing.
