Stopping Penetrating Damp with ISO-THERM Insulation in Poole
How Proofterior Stopped Penetrating Damp and Cold Walls in a Coastal Poole Property Using ISO-THERM Insulation for a Warmer, Healthier Home
Understanding the Problem: Penetrating damp and cold bridging in Poole Property.
Our client in Poole, Dorset, reached out after struggling with a cold and damp external wall that would not dry out, even after repeated decorating. The home’s wall faced the prevailing coastal wind, allowing driven rain and moisture to penetrate through the masonry. During our inspection, we detected elevated moisture readings and visible condensation — clear signs of penetrating damp and cold bridging. These issues are common in Poole’s older coastal homes, where solid walls and salt-laden air increase the risk of persistent damp.
Recommending ISO-THERM Insulation.
Following our survey, we proposed the ISO-THERM thin wall insulation system, a breathable internal wall lining that raises surface temperature, eliminates condensation, and prevents damp from spreading. Unlike traditional insulation, ISO-THERM allows moisture to escape naturally while providing excellent thermal resistance. This makes it ideal for Poole’s maritime climate, where homes frequently experience fluctuating humidity and cold wall surfaces. Our plan aimed to create a warm, dry, and energy-efficient finish that would protect the property long-term without major disruption.
Day 1 – Preparation and Installation.
We began by protecting the work area, removing skirting boards and the picture rail to fully expose the wall. All existing plaster was inspected to ensure a sound base for bonding. The ISO-THERM panels were then applied using a high-adhesion, breathable adhesive designed to promote full surface contact. This step formed a continuous thermal barrier that prevents cold air from transferring through the masonry. Every seam was sealed to eliminate gaps, ensuring the insulation performed as intended against penetrating damp and condensation.
Protective sheeting was laid across flooring, sockets were safeguarded, and furniture was moved for safety. This careful preparation reflects one of the key benefits of our service — from radiator removal to reinstatement, providing a complete, hassle-free experience for homeowners.
Day 2 – Plastering and Surface Restoration.
Once the insulation had fully bonded, we applied a specialist breathable plaster skim compatible with ISO-THERM. This finish ensures that the wall can still “breathe” — allowing trapped moisture to evaporate while maintaining a smooth decorative surface. The plastering process also enhances thermal performance by evening out temperature distribution across the wall. Our technicians used laser-level tools to achieve a seamless finish, ensuring the treated area blended naturally with the rest of the room.
Day 3 – Reinstating Joinery and Final Detailing.
On the third day, we reinstalled the skirting boards and picture rail, matching the home’s original style and proportions. This not only restored the room’s character but also sealed the treatment neatly against moisture re-entry points. All materials and debris were responsibly removed from site as part of our Proofterior waste management process, leaving the space clean and ready for redecorating. The entire project took three days from start to finish — on schedule and with minimal disruption to the homeowner.
Results and Homeowner Satisfaction.
Post-installation testing confirmed a noticeable rise in surface temperature and a significant drop in moisture readings. The room now feels warmer, and no further condensation or damp staining has occurred. The homeowner was thrilled with the quick turnaround and professional finish, noting how much more comfortable the space feels. This project showcases how Proofterior’s ISO-THERM installation in Poole can permanently solve penetrating damp issues while improving insulation and energy efficiency in coastal homes.
Frequently Asked Questions About Damp Proofing in Poole.
1. What are the common signs of rising damp in Poole homes?
Cost depends on the cause, access, and finish. A damp survey in Southampton identifies whether you need a chemical DPC, membrane, ventilation upgrade, or external repairs. Once the survey is complete, you receive a fixed, written quote so there are no surprises.
