Whether the reason for the need of drying and flood restoration is a natural scenario or manmade occurrence; water damage is one of the most unwanted situations that homeowners face. Heavy rains, fire sprinklers going off , a leaky roof, and burst pipes – such incidents can be very destructive to the home itself in the valuables that are contained there. And some of the most important valuables in a home include documents and other paper based items.

Drying Methods

In this day and age where digital products and media have fast become the norm, some documents still remain in its original form. This includes books, certificates, licenses, contracts, photographs, maps, manuals and other documents. Although scanned copies are stored in electronics form; many people still prefer to have the original physical form of the item, either as proof of identity, ownership or because of it’s sentimental value. However, such physical forms are susceptible to water damage with some older items like contracts and old photographs extremely fragile against the damaging effects of exposure to water.

On such occasions where water damage can occur, affecting valuable documents and similar items, the only resort that homeowners can lean on would be drying documents and water damage restoration. Some of these methods can be done by homeowners themselves while other items – particularly the very fragile and expensive ones; may require the services of professional restoration companies.


Use paper towels to remove extra water from the book surface, however, use only plain paper towels without any ink prints. Hold the book at both covers so the pages can be air-blown, without the pages sticking to one another as they dry out. It would also be best to sprinkle the pages with talcum powder to prevent adherence.


Another technique used for water-damaged books is to isolate them inside an enclosed area. Doing this and placing a dehumidifier in can remove the moisture inside the area. Dehumidifiers can be the electromechanical type or the desiccant air-dry distribution type. Again, sprinkle talcum powder on pages to prevent them from sticking with one another.

The two methods above are effective in drying out wet books however the problem would be on how prevent deformation during the drying process. The next method would be the solution to this dilemma.

Vacuum-Freeze Drying Method

Restoration companies utilize the vacuum-freeze drying method to effectively remove moisture from water-damaged books or documents while preventing deformation from occurring as the moisture is drawn out. The freeze-drying process is also known as lyophilization or cryodessication and requires specialized machineries.

In this method, the wet item is frozen at a very fast rate to prevent the water from creating further deterioration on the paper material. A freezer set to -40deg Celsius is used for this purpose. The frozen book is placed inside a vacuum chamber, and the temperature inside the chamber is slowly elevated to thaw the material out. Evaporated moisture is removed from the chamber by the vacuum as the temperature is slowly elevated. To prevent deformation, mechanical placeholders clamp down on the books hindering any movements resulting to warped pages or cover.

Any of these methods are effective restoration techniques. However, homeowners should expect water-damaged books may not fully restore to pre-damaged conditions. Ink smears and tears prior to the recovery process will remain permanent. Recovery though, is still at a high percentage. Again, the homeowners should gauge the worth of the book or document versus the cost incurred by availing these services from restoration companies.

Restoration Techniques:

Photographs Photo prints are some of the most endearing and most priced possessions in a household, particularly if the photographs are old and produced prior to digital photography has been established. Antiques and old photographs are irreplaceable; even when scans and reprints are performed. Although you can never replace the sentimental or intrinsic values of these old photos.

The rule of thumb is, the sooner the better when trying to restore water-damaged photographs.. Within 48 hours, undertake all water damage restoration and document drying, otherwise molds and mildew would occur and create further damage to the photos. The key here is to reduce the humidity and prevent the growth of these microorganisms.

Handle photos carefully and on the edges only. Try not to handle the photo emulsion side directly, otherwise smears and smudges would be occur – rendering the photo useless. Do not pull photos that have stuck together apart; otherwise the photo side will smear beyond repair. Separate by slow rinsing in cold water until the individual photos separate.

Lay each photo flat on paper towels with the photo-emulsion side facing up. Do not use printed paper towels as the ink may transfer to the photo. Slowly air dry them using a low-power air blower or place them inside an isolated room with a dehumidifier.

Digital copies can be excellent backups to these photos and other documents should water-damage occur and affects your photos. This is excellent particularly for newer photos and other documents. Still, this would be a pale replacement to the original print particularly for old photos, certificates, and other documents that have increased its worth and value throughout these years.

Books and Manuals

Books are very difficult to restore because of the bounded pages; which often result to pages sticking or adhering to one another causing irreversible damages. Another issue when trying to restore books is the problem on deformation, which can render the book useless. The most effective method to use that can recover a water-damaged book is the vacuum-freeze drying process. However, the equipment would only be available at document restoration companies and would entail certain costs.

In such cases, the homeowner should decide if the document or book is worth spending dollars with a restoration company. Rare, antique or irreplaceable books would best be restored by professional. Meanwhile attempt repair of ordinary books and manuals using do-it-yourself method. In some cases, the books are not worthy enough to spend energy and resources with and would are simply discarded.

Document Drying

Document drying, depending on the extent of water or moisture absorption, is possible. Either using state of the art technologies employed by professional restoration companies, or through do-it-yourself methods, performed by the homeowners themselves. Such methods include air-drying, dehumidification and vacuum-freeze drying, which are effective enough to restore water-damaged documents to almost its original conditions.

Restoration Techniques: Loose Paper Sheets and Small Compilations

Water-damaged loose paper sheets like certificates and licenses are easier to restore using document drying techniques. Dry loose paper sheets individually by using the air-flow method, either through a low-powered hand blower or through a dehumidifier.

Employ extra care when handling loose paper sheets to prevent further damage like tears or smudges. Remove dirt and grime using clean water, particularly if the water damage is caused by a flood. Layer each sheet on paper towels to dry using an air blower. However, note to use only plain paper towels and avoid using towels with ink prints on the surface.

Restore in bulk loose paper documents and small compilations through the freeze drying methods. Professional restoration companies have sophisticated equipment particularly for the vacuum freeze drying process. On the other hand, freeze wet documents using standard household freezers, and thawing at a later time.
