Our damp proofing services cover rising damp, penetrating damp, condensation, mould, damp proof courses, waterproof membranes and basement tanking. We carry out damp surveys to establish what is causing the issue before recommending work, rather than treating visible signs without considering where the moisture is coming from.

Understanding Damp & Its Effects

Damp can affect properties for different reasons, and identifying the type of damp is an important part of deciding how it should be treated. A damp patch does not automatically mean a property has rising damp, which is why the cause needs to be investigated before work begins.

Rising damp occurs when moisture from the ground travels upwards through walls. Properties normally have a damp proof course designed to prevent this movement, but problems can occur where the existing protection is missing, damaged or no longer working effectively.

Penetrating damp develops when moisture enters a property from outside. Problems with roofing, brickwork, gutters or other parts of the building can allow water to penetrate walls and ceilings. As Diamond Seal also provides building and roofing services, we can investigate related property defects where these may be contributing to the damp.

Condensation is caused when moisture in the air meets a colder surface. It can contribute to mould growth and is particularly noticeable in areas where moisture levels are higher or ventilation is limited.

Common signs of a damp problem can include damp or discoloured patches, mould growth, peeling paint or wallpaper and a persistent musty smell. The signs alone may not establish the underlying cause, so an appropriate assessment is needed before deciding on treatment.

Damp Surveys

A damp survey provides an opportunity to investigate the problem before deciding what work is required. Our damp surveys in Chorley are used to identify the source and extent of damp within the property, allowing us to recommend treatment based on what we find.

This approach is particularly important where different types of damp can produce similar visible signs. Identifying the cause first helps ensure that any subsequent work addresses the actual moisture problem rather than simply covering its effects.

Rising Damp Treatment

Diamond Seal provides rising damp treatment in Chorley for properties where moisture is travelling upwards from the ground through walls.

Treatment depends on the property and the cause identified during the assessment. Where a damp proof course is required, we can install a chemical damp proof course to create a barrier against moisture rising through the wall.

Affected areas may also require further work depending on the extent of the damp and its impact on existing finishes. We will assess the property before recommending the work needed.

Penetrating Damp Repairs

Penetrating damp requires the source of incoming water to be found and addressed. Water may enter through defects elsewhere on the property, which means effective treatment can involve repairing the underlying building problem as well as dealing with the affected internal area.

Our wider experience in building work, property maintenance and roofing allows us to investigate problems affecting different parts of a property. Where damaged roofing or another repair issue is contributing to penetrating damp, we can advise on the work required to address it.

Condensation & Mould Control

Condensation can create persistent moisture on colder surfaces and provide conditions in which mould can develop. Treating the visible mould without considering the moisture problem may mean the issue continues.

Our condensation control in Chorley focuses on identifying why excess moisture is developing within the property and what can be done to reduce the problem. Where mould has developed alongside condensation, we can advise on appropriate measures based on the conditions found.

Damp Proof Course Installation

A damp proof course is designed to prevent ground moisture from rising through the walls of a building. Where an existing damp proof course is absent or no longer providing effective protection, additional treatment may be required.

Diamond Seal provides chemical damp proof course installation in Chorley as part of our rising damp services. We will first assess the property to establish whether rising damp is present and whether a new damp proof course is an appropriate treatment.

Waterproof Membranes

Waterproof membranes can be used as part of a damp proofing system to protect areas of a property against moisture. Their suitability depends on where the damp is occurring and the type of protection the building requires.

We provide damp proof membrane installation in Chorley where this method is appropriate for the property. The required work will be established following an assessment of the affected area.

Basement Tanking

Basements and other areas below ground level can be particularly exposed to moisture because they are surrounded by ground that can hold water.

Our basement tanking in Chorley provides waterproofing for below-ground areas where additional protection against water ingress is required. We can assess the space and recommend a suitable approach based on its condition and how moisture is affecting it.

Damp Proofing Process: What To Expect

1
Assessment

Effective damp proofing begins by establishing where the moisture is coming from. Different causes require different solutions, so our process starts with assessing the affected areas and looking for evidence that can help identify the type of damp involved.

2
Findings & Recommendations

Following the assessment, we can explain our findings and recommend the treatment required. This could involve a damp proof course for rising damp, repairs where water is penetrating the building, condensation control measures, a waterproof membrane or tanking for a below-ground area.

3
Quotation

The work can then be quoted based on the treatment required and the extent of the affected area. Where associated building or roofing repairs are needed, these can also be discussed as part of the work.

4
Aftercare Advice

After treatment, we can provide advice on looking after the affected area and reducing the risk of further moisture problems where appropriate. The exact process will depend on the type of damp and the condition of the property rather than applying the same treatment to every building.

Damp Proofing In Chorley FAQs

What are the signs of damp?

Signs of damp can include discoloured or damp patches on walls and ceilings, peeling paint or wallpaper, mould growth and musty smells. Different forms of damp can produce similar symptoms, so identifying the cause is important before deciding what treatment is needed.

Yes. Diamond Seal provides rising damp treatment in Chorley, including chemical damp proof course installation where this is appropriate. We assess the problem first to establish whether rising damp is present and what work the property requires.

Excess moisture can create conditions that allow mould to grow. Condensation is one common cause of moisture and mould inside properties, although damp can have several possible sources. Establishing why moisture is present helps determine how the problem should be addressed.

Yes. We provide damp surveys in Chorley to investigate damp problems and identify their likely cause. The findings can then be used to determine what treatment or repair work is required.

The cost of damp proofing depends on the cause of the problem, the size of the affected area and the treatment required. Rising damp, penetrating damp and basement waterproofing can involve very different work, so an assessment is needed before an accurate quotation can be provided. Diamond Seal offers free, no-obligation quotations for recommended work.

A damp proof course can be an appropriate treatment where rising damp has been correctly identified and the property requires an effective barrier against moisture travelling upwards through its walls. It should not be treated as a general solution for every damp problem, which is why the cause needs to be established first.
