What We Do

Every Type of Damp. Covered.

From a single damp patch to a full basement conversion — we diagnose the root cause and treat it properly. Basement waterproofing backed by a 10-year written guarantee.

Rising Damp
Most Common

Rising Damp

Groundwater travelling up through walls and floors. We install chemical damp proof courses and replaster with specialist materials for a permanent fix.

Permanent fix
Penetrating Damp

Penetrating Damp

Water ingress through walls, roofs, or around windows. We identify every entry point and apply targeted waterproofing repairs to stop it at the source.

Full external inspection
Condensation & Mould
Health Risk

Condensation & Mould

Black mould and streaming windows signal poor ventilation. We treat existing mould, improve airflow, and apply anti-condensation coatings to keep homes healthy.

Mould removal + prevention
Basement Waterproofing

Basement Waterproofing

Tanking systems and cavity drain membranes to create genuinely dry, usable basement spaces — whether for a utility room, office, or extra living area.

Add living space to your home
Timber Treatment

Timber Treatment

Damp conditions allow woodworm and fungal decay to take hold. We treat and replace affected timbers and resolve the underlying damp cause to prevent recurrence.

Woodworm & fungal treatment
Dry Rot & Wet Rot
Act Fast

Dry Rot & Wet Rot

Fungal decay can spread rapidly through a property. We contain it, treat with specialist fungicides, and replace any structurally compromised timber.

Containment & specialist treatment
Cavity Wall Ties

Cavity Wall Ties

Corroded or missing wall ties cause cracking and structural movement. We survey and replace them using specialist stainless steel helical ties with minimal disruption.

Structural survey included
Repointing & Repairs

Repointing & Repairs

Cracked or eroded mortar joints let water directly into the wall structure. We repoint using the correct lime or sand-cement mix to match the original construction.

Damp Surveys

Not sure what type of damp you have? Our thorough surveys include moisture readings and a full written report — essential for property purchases and housing association works.

Full written report included
Internal Wall Insulation
Energy Saving

Internal Wall Insulation

Cold walls cause condensation, mould, and heat loss. We install the Wykamol Isotherm Tiwi system to create warm, dry walls — eliminating condensation at source.

Stops condensation — warmer walls
Why EverDry

We Fix Damp.
Properly. Once.

A small damp patch today can mean timber rot, crumbling plaster, and mould throughout your home within months. The longer it's left, the more expensive it becomes.

We don't apply a surface fix and move on. We find the root cause, treat it properly, and back our damp proofing works with a 20-year written guarantee, and basement waterproofing with a 10-year written guarantee. While we hold contracts with housing associations across Newport and Cardiff, the majority of our work is with private homeowners — and that's exactly where we want to grow.

What Our Customers Say

Verified reviews from homeowners across South Wales. Also see us on Checkatrade.

Had rising damp in two ground floor rooms. EverDry came out quickly, explained everything clearly, and the work was done neatly with minimal disruption. The replastering looks great. Very happy with the result.

Rising Damp

Used EverDry for a pre-purchase damp survey. Detailed report within days. Honest advice — they told me one damp patch was condensation and didn't need treating. Really appreciated the straight talking rather than upselling.

Black mould in the bedroom had been a problem for years. The team sorted the ventilation and treated the walls properly. Over a year later and there's been no sign of it coming back. Wish we'd called sooner.

Our surveys are completely free with no obligation. We visit the property, carry out a full inspection with moisture readings, and provide a clear written report at no charge.
Most rising damp treatments are completed in 1–2 days. Larger jobs such as basement waterproofing or extensive timber work may take 3–5 days. We'll give you a clear timeline in your written quote.
Damp proofing works are backed by a 20-year written guarantee. Basement waterproofing is covered by a 10-year written guarantee. In both cases you receive a full written report detailing exactly what was done.
Yes. Persistent damp encourages black mould growth (Stachybotrys chartarum) which is linked to respiratory problems, allergies, and worsened asthma. It's particularly harmful to children, the elderly, and anyone with a compromised immune system. We recommend acting quickly.
Not usually. Most treatments are carried out with you at home and with minimal disruption. We'll advise you in advance if any specific areas need to be vacated temporarily.
Both — but private domestic work is a big focus for us right now. We hold contracts with housing associations in Newport and Cardiff, and we bring exactly the same professional standard to every private home we work in.
