Apex Lofts and Construction recently completed a loft conversion for me and I couldn’t be happier with the result. From start to finish they were fantastic. The whole team were professional, reliable, and kept everything on track. Communication throughout the build was excellent, I was always kept informed and felt reassured at every stage. The quality of workmanship is first class and the finished loft has completely transformed my home. I wouldn’t hesitate to recommend Apex to anyone considering a loft conversion or building project.Posted on AdamTrustindex verifies that the original source of the review is Google. I am a property developer from Brighton and have used many builders over the years. Josh (Apex) are the best builders we’ve ever used and we wouldn't hesitate to use them again. A lot of builders out there will quote low to get the work, then add extras making the overall development expensive with nasty surprises. We had none of that with Apex. It was straightforward, honest, fast, competitively priced, high quality work and they kept to timelines. It was an absolute pleasure working with Apex.Posted on Shaheen ShahmirzadiTrustindex verifies that the original source of the review is Google. Apex Lofts and Construction renovated our house from top to bottom and did a brilliant job. What they did Damp proofing and insulation throughout New kitchen fitted from bare walls up New bathroom with all fixtures and tiling Three new skylights installed and made watertight Full painting and decorating inside Quality of work The finish is clean and solid. Walls are straight, joins are neat, tiles are even, and the skylights don’t leak (even in heavy rain). The kitchen units are level and the doors line up perfectly. They clearly take pride in the details. Project management They turned up when they said they would, kept the site tidy, and coordinated all the trades so we weren’t left waiting around. Any changes were explained in plain English with options and costs before they did anything. Communication Easy to reach, quick replies, and regular updates with photos. If something wasn’t possible, they said so and offered sensible alternatives. Time & budget They stuck close to the schedule and the final bill matched the agreed quotes, apart from a couple of extras we asked for (priced fairly and agreed in advance). Respect for our home Floors covered, tools packed away each day, and neighbours kept happy. Rubbish was removed, not left for us to deal with. Aftercare They came back promptly for a small snag list and sorted it without fuss. Bottom line Reliable, skilled, and straight-talking. If you want your house done properly, use Apex Lofts and Construction. We’re very happy with the result and would hire them again without hesitation.Posted on Tracey BaynhamTrustindex verifies that the original source of the review is Google. We are delighted with the work Apex Loft conversions did on our house. It’s transformed our living space. They converted our loft into a new master bedroom and en suite and the finish is excellent. Every person that worked on the job was polite, respectful and always turned up on time. Really impressed with the speed they worked at too. We would highly recommend them to anyone.Posted on Simon MatterfaceTrustindex verifies that the original source of the review is Google. After comparing a few local companies, meeting Josh we decided to use Apex for our loft conversion, and we couldn’t have made a better decision. From the the outset the team showed their capability, professionalism and craftsmanship. In typical British summer weather, the night after they opened our roof, we had unplanned biblical wind and rain! Inevitably we had a leak, so I called Josh at 8pm, and within 10 minutes he had some of the team up on the roof fixing the covering. This to me is a sign of a very good company. Apex added 1 large double aspect main room, 2 double bedrooms and a small shower room in to our loft, and we cannot be happier with the result. At each stage, Josh and the team guided us through, discussed options and offered helpful advice when needed. I would definitely recommend Apex to anyone thinking to doing a loft conversion or extension.Posted on carlos adieTrustindex verifies that the original source of the review is Google. We appointed Apex to undertake our rear extension, plus a reconfiguration of the ground floor. Throughout the process, Apex has been excellent. Josh, the owner, has been invaluable from the first introduction to the final completion, and has been flexible throughout the project, plus has responded in resolving any of our issues. The team that undertook the work were also helpful and explained what was expected and how it would be done. Everyone was friendly and respectful and the quality of work was excellent. Highly recommend.Posted on Glynn NicholasTrustindex verifies that the original source of the review is Google. Absolutely fantastic company. Had a loft conversion on our 1 bed bungalow and what an amazing difference. Had a few issues along the way with various other parties but Apex themselves would do everything they could to sort it out ASAP. Highly RecommendPosted on Saba DehdashtiTrustindex verifies that the original source of the review is Google. From the first contact Josh and his team were brilliant. Builds can be stressful, particularly with children, however apart from the usual minor things, which were sorted swiftly, it couldn’t have gone more smoothly. I had someone on site every single day of the 8 weeks it took to complete my loft. Josh adapted to my many requests, patiently! And it was worth it, our loft is incredibly and better than expected. Great team of builders and trades, all top class and the finish speaks for itself. Thanks team Apex!Posted on slogo heinzyTrustindex verifies that the original source of the review is Google. Many thanks to Josh and his team for completing major refurb works in 2023 at our bungalow in Worthing. From the start, the scope of works was clearly defined and price broken down into 20 installments over the duration of our new loft dormer and total downstairs refurb .We lived in the property throughout and Apex skillfully and thoughtfully planned the works around us to minimise disruption. They are an experienced team and bring in trusted third party tradesman where needed. All in all, we are very happy that we chose Apex and Josh was a personable and very knowledgeable guy to work with throughout.
Every job begins with a comprehensive assessment. We survey the affected areas and use moisture readings and inspection methods to determine the type and extent of the damp issue.
There’s no one-size-fits-all solution for damp. We tailor each treatment plan to suit the construction type, location, and severity of the problem.
All work is carried out by skilled professionals to a high standard of workmanship. Once complete, we provide the appropriate guarantees so you can move forward with confidence.
Moisture travelling up through walls from the ground, often due to failed or missing damp proof courses. Common in older buildings.
Water ingress through external walls, roofs, or structural defects, often worsened by poor maintenance or exposure to the elements.
Often caused by poor ventilation or insulation, condensation can lead to mould, damp patches, and health concerns.
Below-ground spaces are particularly vulnerable to lateral damp and water ingress. We offer targeted protection to make these areas dry and usable.
From loft conversions to full refurbishments, we help you make the most of your home’s space, flow and value, with solutions designed around how you live.
With decades of hands-on experience and a West Sussex base, we’ve transformed countless homes and commercial spaces throughout the region.
Our in-house team and specialist partners deliver high-quality results backed by a commitment to compliance, attention to detail, and long-term performance.
We carry out an in-depth inspection to identify the root cause of damp, using moisture detection tools and visual checks to assess the severity and affected areas.
Based on our findings, we provide a clear explanation of the issue and propose a tailored solution that addresses the specific cause and type of damp.
You’ll receive a detailed quotation and breakdown of the required work, with everything clearly outlined before we begin.
Our team carries out the treatment using industry-proven methods suited to the property type and condition, ensuring the highest standard of work throughout.
Once the work is complete, we conduct final checks and provide clear advice on aftercare, maintenance, and any ventilation or structural improvements that may help prevent future issues.
Should you have any questions after the work is completed, we’re here to help. Our ongoing support ensures your property continues to benefit from effective damp protection.
If you’ve noticed signs of damp in your home or commercial property, don’t wait for it to get worse. Speak with Apex Lofts & Construction to arrange a survey or consultation with a member of our team.
Common signs include peeling paint or wallpaper, musty smells, black mould, salt deposits on walls, or damp patches that don’t dry out. If you notice any of these symptoms, a professional survey can help identify the cause and appropriate solution.
Period homes often lack modern damp proof courses or insulation, making them more vulnerable to rising damp, condensation, and penetrating moisture through solid brick or stone walls. We specialise in treating damp in older and character properties while preserving their integrity.
Not always. While a damp proof course may help in cases of rising damp, other forms, such as condensation or penetrating damp, require different approaches. We assess the cause before recommending a treatment.
Generally, no. Most damp proofing work is considered internal maintenance. However, if your property is listed or in a conservation area, you may need listed building consent. We’ll advise on any permissions required during the survey stage.
This depends on the type of damp and the size of the area affected. Some treatments can be completed in a few days, while more extensive basement or structural works may take longer. We provide a project timeline as part of our proposal.
Yes. We regularly work in below-ground environments where lateral moisture and poor drainage cause persistent damp problems. We offer effective solutions to keep these areas dry, usable, and protected long-term.
It can help, but condensation is usually a ventilation or insulation issue. We assess the root cause and can recommend additional improvements such as passive ventilation or changes in heating strategy to reduce moisture buildup.
In most cases, yes. We aim to minimise disruption and carry out work as efficiently and safely as possible. If an area needs to be isolated during treatment, we’ll advise you in advance and plan accordingly.
Our treatments are designed for long-term protection and include recommendations to prevent future moisture issues. Like any building system, effectiveness also depends on ongoing maintenance and ventilation, which we will advise on post-installation.
Yes. We provide appropriate guarantees for our work depending on the treatment type and scope. This gives you peace of mind that your property is protected well into the future.
