Verified handyman network in Barcelona

We do waterproofing in Sant Just Desvern. We visit the property, assess the job, give you a clear price, and get started. The second service is plumbing for homes with old installations. Replacement of lead pipes when they appear, bathroom renovations that respect the original layout or modernise it according to the client's preference, installation of modern electric water heaters. For some houses with a rear gallery, we also handle the drainage of rainwater, which can cause problems during heavy rains.

How we work

Call us, message us on WhatsApp, or request a quote online — we'll respond in under 10 minutes during business hours. The main service is electrical upgrades in traditional town houses. Replacement of old fuse boxes with modern REBT compliant ones, running new circuits while respecting traditional walls and archways without damaging the masonry, installing sockets and outlets where there were none before. The subtlety lies in carrying out the upgrade without destroying the traditional aesthetic of the house; homeowners in Crevillente highly value preserving the character of their inherited property. The construction process is quite clean. We first assemble the metal structure of galvanised steel profiles, screwed to the floor and ceiling. Electrical wiring, water pipes if any, are run through, and the interior is filled with rock wool or glass wool insulation, which provides considerable acoustic insulation. Plasterboard panels are screwed to both sides. They are joined with fibre tape and jointing compound, sanding between coats until a completely smooth surface ready for painting is achieved.

When to call for waterproofing in Sant Just Desvern

Yes, this is the subtlety of working in old houses in Crevillent. We study the optimal route, use embedded or surface conduits as appropriate, and repair the masonry with judgment when openings are necessary. Yes, in houses with rear galleries or typical old town courtyards. Cleaning of drains, replacement of old downpipes, repair of waterproofing when there are infiltrations. Yes, considerably when filled with rock wool or glass wool. Medium insulation: 35-40 dB with two boards and full filling.

Materials and brands

30 days on labour for each trade. Manufacturer's official warranty on sanitaryware and materials. What seems like a simple, small, full bathroom or kitchen renovation is technically complex, combining several trades that must work in coordination in a limited space under tight deadlines. If coordination fails, deadlines double, budgets spiral out of control, and the final result has visible defects you'll have to live with for the next ten years. The difference between a well-done and a poorly-done renovation is rarely in the materials (they are the same in both cases) but in the design, coordination, and quality of each trade. Medium-high quality selected for the quote. We also work with client-supplied materials.

Indicative pricing

The price for waterproofing in Sant Just Desvern typically ranges between €170 and €5000. The final figure depends on the property's condition, materials, and work time. We always provide a fixed quote before starting. The project begins with a technical visit where we measure the current space and identify what can be modified and what is structural and untouchable. Then, we discuss with you what you want to achieve. Do you just want to modernise while keeping the current layout, or completely reform the layout (typical in bathrooms where a bathtub is removed to install a large shower)? We create an initial sketch, show it to you, and adjust it based on your feedback. Only then do we prepare a detailed quote by line item with specific chosen materials. Design in your style, detailed quote by item, and committed execution timeframe.

Frequently asked questions

How long does it take to build a plasterboard partition?
A standard 3-4 linear metre plasterboard partition: 1-2 days with two people. Faster if it does not require complex internal installations.
Does it provide acoustic insulation?
Yes, considerably when filled with rock wool or glass wool. Medium insulation: 35-40 dB with two boards and full filling.
Can a heavy TV be hung on plasterboard?
Yes, by locating the metal support profiles behind the plasterboard with a detector and screwing to the profile. Without locating them, use a specific plasterboard plug with limited maximum load.
Does a false ceiling affect natural light?
No, if you only lower it 8-10 cm from the original ceiling. For greater drops in high ceilings, the perceived amount of light does change noticeably.
Is a license required for a plasterboard partition?
For internal distribution without affecting structure or major redistribution: responsible declaration. Significant change in distribution: minor works license.
