We do waterproofing in El Guinardó. We visit the property, assess the work, give you a clear price, and start. Homes on the front line of the sea have specific problems requiring extra treatment. Saltpetre settles on the wall and, with damp, migrates into the substrate. When we paint over it, the salts continue their path and peel off the new paint within months. The solution is washing with specific chemicals before painting, neutralising, and applying a siloxane-type paint that allows the wall to breathe without letting water in.

How we work

Call us, message us on WhatsApp, or request your quote online — we reply in less than 10 minutes during business hours. The second step is priming. We apply a specific sealant primer that penetrates the substrate and creates a uniform adhesive base for the final paint. Without the correct primer, the final paint may not adhere well to the substrate and can peel off quickly. It's the step most often skipped in quick repaints but the one that most impacts durability. The third step is applying the final paint. For large facades, we use airless sprayers for a uniform, fast finish. For terraces and detailed areas, we use good quality rollers. We always apply two cross-coats (the first vertical, the second horizontal) to ensure uniform coverage without marks.

When to call for waterproofing in El Guinardó

Damp from filtration requires extra treatment. If water is entering from the roof, the roof must be repaired first. If it's rising damp from the ground, chemical barrier injection is required. Painting over without treating the source is always a waste of money. Yes, using chemical barrier injection methods and waterproofing mortars. We guarantee the treatment for 5 years. Painting over damp without treating the cause never works; it always comes back. Toilets with high-level, low-level, or concealed cisterns, wall-hung models on concealed frames, rimless models without an interior rim which are more hygienic and easier to clean. Basins on pedestals, inset into countertops, wall-hung with exposed traps. Shower screens and bath screens that are fixed, sliding, folding, or corner units. Standard bathtubs, single whirlpool baths, and low-profile shower trays when a full renovation is done.

Materials and brands

The most common mistake is repainting a facade with interior paint or cheap exterior paint for large areas. 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 cheap and professional paint is relatively small. The difference in years of durability more than makes up for it. Official manufacturer's warranty for the paint, plus our cover for the labour. Have you bought a property in the area and the facade or terrace has yellowed, peeling, or stained paint? 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, with over 300 days a year of direct UV radiation. Marine saltpetre that settles on surfaces near the coast. Rare but torrential rains that wash away layers. And Saharan dust that embeds itself in the pigments. Cheap white paint resistant to UV will last three summers in these conditions. Specific paint for coastal climates with a reinforced UV filter will last 8-10 years looking good.

Frequently asked questions

How long does it take to paint a whole home?
An 80-100 m² home with a crew of 2 people takes 3-4 days to paint with two coats. If walls need repairing, smoothing out textured plaster, or treating damp before painting, add 2-3 days.
Do you paint external facades at height?
Yes, up to the second floor with our own lifting platforms. For taller buildings, we work with specialised companies with permits for vertical works.
Do you treat rising damp?
Yes, using chemical barrier injection methods and waterproofing mortars. We guarantee the treatment for 5 years. Painting over damp without treating the cause never works; it always comes back.
Do you do small full renovations?
Yes, bathrooms and kitchens up to 15 m² we do them completely: demolition, plumbing, electricity, tiling, sanitaryware, and painting. For larger renovations, we refer clients 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'll move heavy items from the centre of the room.
