We do waterproofing in El Baix Guinardó. We visit the property, assess the work, give you a clear price, and start. Damp from leaks requires extra treatment. If water is coming in from the roof, the roof must be repaired first. If it's rising damp from the ground, it requires chemical barrier injection. Painting over without treating the source is always a waste of money.

How we work

Call us, message us on WhatsApp, or request your quote online — we'll reply in under 10 minutes during business hours. The first step is substrate diagnosis. If the existing paint is well-adhered, we cover it. If it's peeling, we remove it completely with a spatula and sander, leaving the substrate clean. If there are structural cracks (not superficial ones), we treat them with elastic filler that accommodates minor building movements without re-cracking. If there are saltpetre stains or white efflorescence, we remove them with a specific chemical product and neutralise before painting. The third step is applying the final paint. For large facades, we use airless spray guns for a quick, uniform finish. For terraces and detailed areas, we use a good quality roller. We always apply two cross coats (the first vertical, the second horizontal) to ensure uniform coverage without brush marks.

When to call for waterproofing in El Baix Guinardó

Homes on the frontline of the sea have specific problems that require extra treatment. Saltpetre deposits on the wall and migrates into the substrate with moisture. When we paint over it, the salts continue their path and cause the new paint to peel off in a few months. The solution is washing with specific chemicals before painting, neutralisation, and application of siloxane-type paint that allows the wall to breathe without letting water through. Yes, using chemical barrier injection methods and waterproofing mortars. We guarantee the treatment for 5 years. Painting over untreated dampness never works; it always returns. There are two very different scenarios when we talk about sanitaryware. The first is a single replacement. A cracked toilet, a basin broken by a falling bottle, a bathtub being converted into a shower tray for accessibility. These are half-day or one-day interventions at most that don't require major work. The second is a complete bathroom renovation, where we change everything at once and coordinate multiple trades.

Materials and brands

We check the facade's condition and choose the appropriate paint system for the material and exposure. Have you bought a property in the area and the facade or terrace has yellowish, peeling paint or whitish stains? It's not due to poor quality of the original paint. It's due to the harsh exposure conditions of the area. The Costa Blanca combines four factors that destroy standard exterior paints. Intense and constant sun, over 300 days a year of direct UV radiation. Sea saltpetre that deposits on surfaces near the coast. Rare but torrential rains that strip layers. And Saharan dust that embeds itself between the pigments. An economical white paint resistant to UV would last three summers in these conditions. A specific paint for coastal climates with reinforced UV filters lasts 8-10 years looking good. Official manufacturer's warranty plus our labour coverage.

Indicative price

The price for waterproofing in El Baix Guinardó typically ranges from €170 to €5000. The final amount depends on the property's condition, materials, and time spent working. We always provide a fixed quote before starting. The most common mistake is repainting a facade with interior paint or cheap, large-surface exterior paint. It works the first year but visibly degrades by the second. You need to invest in specific exterior paint with acrylic or silicone resins, quality UV filters, and impact resistance. The cost difference per litre between economical and professional paint is relatively small. The difference in years of durability more than makes up for it.

Frequently asked questions

How long does it take to paint an entire home?
An 80-100 m² home with a 2-person crew takes 3-4 days to paint with two coats. If walls need repair, smoothing out textured finishes, or dampness treatment beforehand, add 2-3 days.
Do you paint exterior facades at height?
Yes, up to the second floor with our own lifting platforms. For taller buildings, we work with specialised companies with vertical work permits.
Do you treat rising damp?
Yes, using chemical barrier injection methods and waterproofing mortars. We guarantee the treatment for 5 years. Painting over untreated dampness never works; it always returns.
Do you do small, complete renovations?
Yes, bathrooms and kitchens up to 15 m² we do completely: demolition, plumbing, electrics, tiling, sanitaryware, and painting. For larger renovations, we refer to a specialised construction partner.
Do you cover and protect the house before painting?
Of course. We cover floors with hardboard or thick plastic, protect sockets and skirting boards with tape, and move light furniture. We move heavy items to the centre of the room.
Is the quote free?
Yes, free and without obligation. A prior visit to measure and check the wall condition. A detailed quote broken down by item within 24-48 hours.
